Trigger fish, IIRC, deal with similar "thorny" customers, all the time. So, they know how deal with and consume prickly subjects. The issue with other predators is they don't know be wary of way/direction they consume the Lionfish. (Note: that Grouper tried eat it from the side and thus went, "Yuck/Owww, Patooey!" With it. Eaten from the front, they have no issue that I've either seen or heard about?)
Agreed. It would have happened anyway. This just speeds up the learning process. I think some species of birds have recently learned on their own to eat Japanese beetles.
Our lionfish are quite rare, and they are eaten by both sharks and our giant Javanese Moray eels. These are resident in Mauritius. Both have poisoned flesh as a result and are not eaten locally
The Queen Trigger, my favorite aquarium pet I've ever had. They are voracious eaters. The one in this video is huge. Thanks so much for this video it's been a long time since I've seen one!
@OceansUnknownwithToddKortte I had mine a long time ago she was tiny the size of a quarter. I lost her after hurricane Andrew. We had no power for a long time. She would bite my finger and would not let go. So tiny yet so aggressive. She would eat everything I gave her, she especially loved shrimp. I've never forgotten that little beast. She had quite the personality. Some people say triggers are much like dogs.
We can't answer your question. What happened to the grouper did the spiks injure it? The trigger fish nibbled at the exposed flesh could it eat a live lion fish defending itself? Have they started discouraging people feeding them to sharks because they die.(Years ago that might have been thought of as a bonos). A fish will always investigate a potencial meal but they don't know the danger an invasive fish offers.
The Grouper left the scene. The Grouper is too small, it will eat the Lionfish when it gets older. The Triggerfish will not eat the Lionfish whole. Like you mentioned, it knew to look for the exposed flesh. Sharks eat the Lionfish in the Red Sea.
The main reason lion fish are a problem isnt that they are toxic its that they are great at hunting, many fish have spines so most predators have ways of getting around them the main issue is lionfish look pretty unique so a lot of predators dont have that instinct to go after them like they do other fish. Lionfish are wiping out small fish not big ones.
Assume you already know triggerfish feed on other spiny venomous creatures like the queen of thorns starfish and urchins, so if any predator is going to figure out how to get past the lionfish's defenses, triggerfish already have some of the skills
Lionfish are more capable of evading attacks and fighting back than the triggerfish's other prey with venomous spines, so might be tough, but not out of the realm of possibility.
I find it so bizzare when saying 2017, followed by "back then"... In my head I'm like, that wasn't that doesn't feel like 7 years ago. Time is moving too fast.
The thing is that in order to teach the predators how to hunt lionfish, you have to actually introduce them first. They won't know they're edible if you don't give the lionfish to them to taste.
This is not controversial at all, the lionfish is an invasive species in the Atlantic ocean and can we get sharks, groupers, triggerfish or any other native predator to see them as food so much the better, because the lionfish is destroying the fry/small species of native coral fish at an alarming rate and fish are better and more efficient hunters both considering time, money than divers ofc it is good with the divers too but that is a losing battle since lionfish reproduce much faster than all of the professional divers put together.
I think all of this is excellent, both with the sharks and with the triggerfish. Perhaps that grouper was a better too small or got some spine from the speared lionfish. Fish are turning out to be smarter than we knew and there are an increasing number of examples of different species, even different phyla (like gobies and shrimp) working together for safety or hunting. Like with ravens - which can find carcasses they cannot open - transferring their cooperative behavior from wolves to human hunters, these fish are highly motivated to learn a new behavior that gets them food.
Hi I think it’s great teaching these fish that they can actually eat the lion fish since it’s an invasive species , then they can help defend the reef against the lion fish 🙂👍❤️🇦🇺
I understand the reluctance by many to "encourage" spear fishing divers to feed the non-native Lionfish to various native fish species. The worry here being behavioral alteration in the fish in the form of habituation. Most wildlife scientists would discourage this activity because individual fish may then associate "food" to "diver," altering the fish's behaviour around other humans coming into that environment. Loss of natural fear of humans may then result in injury or death at the hands of unscrupulous humans who would then bait habituated fish closer in for an easy kill (because humans just can't resist cheating). I did have a concern that fish attempting to eat the lionfish might be accidentally injected by a venomous spine in the first attempts to take the Lionfish from the divers. There is, as the narrator alludes, a learning curve for native species to learn how to successfully kill and then disarm non-native species like Lionfish. My own observations with Great blue heron catching, repositioning, and breaking the venomous spines off Plecostemus before consuming the fish might be insightful here. I'm not convinced that spear fishing divers are actually teaching native fish to hunt and consume Lionfish simply by offering them dead Lionfish to eat. Rather, I suspect that, at least initially, it's just limited to habituation of the fish chosing to respond to a food cue. Clearly, an experiment is required to tease out whether this hypothesis can be supported or debunked, with replication necessary for a definitive answer. Anyone game for that?
I feel like we wouldn't bat an eye if fish were taking the dead lionfish from another animal. I think as long as the predators aren't associating humans as food, or becoming dependent on humans for food, I don't see why anyone should worry. In the end if some of the higher level predators start associating the lionfish as a food source it will help the reefs in the long term. I don't normally advocate killing an animal for no reason and honestly it's not the lionfishes fault it is there, it's humans fault, but they do so much damage to the reef they can't be left alone. I feel bad for the thousands upon thousands of lionfish killed but it's less of a threat then to lose the entire reef's ecosystem.
Doesn't surprise me, a Trigger will eat anything..... seriously though, one of almost all species of Triggerfish favorite things to eat are sea urchins, which have lots of spines... I would guess that it is associated the spines of the lion fish with the spines on an urchin
Avid lionfish hunter here. It’s not a good idea to feed wildlife. From eels to snappers, groupers and sharks that all of the sudden only follow divers, to more stressful scenarios where you have to stop hunting because there’s a problem from these practices. Today, even Florida salt water anglers that take tourists out fishing are reporting incidence in sharks and other larger pelagic fish attacking a fish on the line while the angler attempts to land the fish. The norm now is for a portion of the fish to have a chunk eaten off already before it’s out of the water. This isn’t normal behavior and it’s likely a result of a learned behavior associated with feeding. Just one example of why experts are correct when they recommend not feeding wildlife. My 2 cents. Cheers!!!
Forgot to mention. I recommend using a hard plastic container to keep your lionfish catch. There are many options out there. Zookeeper is one of the best. Hope this helps. Cheers!
Yes this is so true. I plan on making a video on the same reefs in Belize comparing 2014 to 2022. You can see a significant difference in the behavior between those 2 years I have on video. Its a night and day difference.
Could be running out of decent food to catch, so maybe it is taking advantage of the spear fishing. Also, many people think fish stay in one location forever, it is possible this trigger fish hunts along the coast and stays near fishermen and divers for this reason? Maybe even had a diver feed it once, so it learned the tiger fish is eatable and remembers the divers give out free easy meals.
Some think feeding the sharks is only damaging the behavior. Shark now look to divers for a free handout, and the sharks are not hunting the lionfish on their own.
The grouper won't, eat it because it would have to eat the poisonous barbs when it swallows it whole, but the trigger fish can just rip it apart and avoid the barbs
Yes that is part of it. The trigger also knows to look for the exposed flesh. They feed a lot of shark in this area of Cuba. Maybe the trigger learned to follow the divers?
It teaches sharks to associate divers with food, and some believe the sharks are not hunting the Lionfish on their own. The sharks are not circling divers on the reefs in Belize to see if you are spearing Lionfish. This did not happen 8 years ago. It makes for fun diving to see the sharks, so that is good for tourism. But some people think we are changing too much with the behavior of sharks by feeding the Lionfish to the sharks.
Since lion fish are apparently good eating, it might be worth trying to push for a bounty program at a level that encourages commercial diving and harvesting operations. Take the pressure off other species commonly targeted for the dinner table.
I still find it fascinating that an animal can be protected and endangered in one area and actively hunted in another. I understand why, still, i find it fascinating thiugh.
My wife I spent years snorkeling in the Bahamas. We were on the island of Eleuthera, at a place called Raibow Bay. One of the most beautiful locations on the planet. Not exaggerating. Look it up. We snorkeled way out. Long story short - and it's a long story - my wife was attacked by a reef shark there. It did a figure 8 "threat dance" before attacking her and unfortunately, we didn't understand what was happening. We were not spear fishing and we didn't know spear fishing had become so common. As my wife was recovering, the locals explained that reef sharks around the island now hunt down humans because they expect to be fed lionfish from spear fishers. Several fishers get bit just from carrying the pole - as the reef sharks now associate a free meal with the pole. Sadly, my wife will never snorkel again. Sometimes she still wakes up screaming from nightmares. We had to find new hobbies. I'm not passing judgement, the lionfish need to be dealt with. But just sharing our experience.
Yes that is why most fish do not eat the Lionfish. The Lionfish eats all the fish. The math is upside down, that is why the Eco-system is all mess up in the Caribbean. The fish know not to eat the spines.
the spines are, the fish isn't. Some of those sharks, eels, and other fish seem to be able to eat the lionfish without being hurt by the spines poke. I think the toxin it uses just causes pain, it won't actually kill anything past a certain size.
I dont think its a problem, its not like there are enough divers to support the fish and it just shows them a new food source, fish are smarter then people realize. Trigger fish are actually quite capable of learning and if it realizes it can catch lionfish it might start going for them, they can be surprisingly predatory.
That's true, but with all the other environmental changes, like coral bleaching, many species are not able to adapt fast enough. It's too much all at once.
@@joshuacook2 Too much for what? For all species to adapt? Of course. Nature is competitive, and if you can't adapt fast enough, your form stops being alive. Other life evolves to take your place. I'll bet sharks are going to be fine, they have a pretty good record.
How do you protect the predatory fish from the venomous spines? Aren’t they still venomous even when the lion fish is freshly killed? I know I would never trust anyone who offered me a salad made of fresh cut stinging nettles.
From personal experience, enuring sharks, or any other potentially aggressive fish, to take lionfish from a spear can have rather stark unintended consequences… My teammates and I hunt lionfish regularly, at depths between 40 and 60 meters, racking up significant decompression obligations. At one point a few years back, we had to abandon a favourite hunting spot as we were being harassed, constantly, by a 2m nurse shark that we believe had learned to associate not only divers, but yellow pole spears too, with free meals. Fending off it’s continual advances for 40 minutes grew not only tiresome, but put the team at risk of violating the decompression schedule. That is a dangerous situation… We’ve recently had a few divers have unnerving encounters with sizeable free swimming green morays seemingly looking for handouts… Again, no bueno… I am of them mind that divers should lookout for the reef ecosystem by hunting as many lionfish as possible, but please do so in a responsible way and take your haul home to eat… They are great for ceviche and make really nice fish-n-chips!
Yes, you are so right about the yellow pole. Some grouper look for the diver with the yellow spear. Thank you for this comment and the information. Do you notice more lionfish at deeper depths than at recreational dive limits?
@@OceansUnknownwithToddKortte - Where I’m at, Utila Honduras, the shallower reefs are heavily hunted so that segment of the lionfish population seems to be fairly in check. Since there’s only a handful of divers that regularly tech dive here, it’s easier to get a significant haul down deep. A few years back we participated in a research project where the goal was to sample and age the lionfish population from the shallows down to 100m depths to see if there a correlation between depth and age and/or size - the theory being tested that lionfish tend to migrate downward as the mature. It seems there is an aggregation level, here, on the sand shelf that surrounds the island at depths between 35m to 70m. Below that, on the deep walls, they’re harder to find… Though, our deepest sighting was a bit too deep to be hunting at around 130m!
Why don't you think the trigger fish could reasonably be expected to associate you, a large mammal, with access to feed? Time aside, the fish's brain could recognize a behavioral scheme of predation anyway, and would not even need to know anything about you necessarily to see the lionfish is incapacitated anyway.
Some people think feeding the sharks is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
I always thought groupers were the most intelligent fish. I’ve seen groupers hunt and corner lion fish. Surprised you see this behavior on a trigger fish. It is even aware of its spines. Amazing
True. Some people think feeding the sharks and fish is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
I feel like the difference in the way the triggerfish and grouper eat their food has a lot to do with why one ate it and the other did not. Triggerfish have enough teeth and a small enough mouth that allows them to peck and take small niblets at a time. This combined with the fact that it can probably detect the fish is now dead and spines disarmed, it has no problem going after it. However, you can still see it swimming backwards sometimes to still keep the spines at bay and have access to the meaty bits. Like it still knows it's a threat, just not a live one. The grouper doesn't have the teeth necessary to take those small niblets, if I'm not mistaken it's basically a vacuum eater and has a handful of teeth to hold onto the fish, but not chunk bits off. So to the grouper, those spines attached to the carcass still pose a huge threat. That's my take on it anyways :). Solid footage though, that Triggerfish is beautiful.
Fish are learning divers = slot machines with high payout. They are eatting what the divers give them, because they see them as safe, like how when a aquarium fish learns you, they always swim to the glass when they see you because they know its time for feeding. Eventually they will learn to eat the lionfish naturally, but its most definitely due to the divers influence. But in reef tanks, one of the most annoying thing is getting your fish to eat what you want them to eat. Sometimes it happens over time with routine, other times the fish will die before it eats something its not native to. This is why most of us quarintine the fish not just for observation, but to also start training it to eat the foods you want them to eat. As for is it OK? absolutely... There is no otherway to get rid of an invasive species other then using a natual species to hunt it out of exinction before the other members of the ecosystem falls off due to it.
@@OceansUnknownwithToddKortte Can you recommend the best city for a diving home base? Do you have to fly from USA to Havana, or are there direct flights from the USA to the diving bases?
The invasive fish needs to be kept under control. The idea that it might be a bad habit to form looking for food from humans, but the lionfish is a human-related problem too. That triggerfish was beautiful.
@@OceansUnknownwithToddKortte A pouting mouth may be advantageous over a gaping maw in this case. Fishes are smart in their own ways. Urchins are well armored but they have predators. I will watch again and pay attention to its line of attack. :) Ah it may be the dorsal spikes. They get stung on their palate. The trigger fish shred and nibbles but avoids the dorsal spikes.
if they are invasive i see no problem with either keeping it or feeding other fish on the reef with it. If you teach the other reef fish to eat the lionfish then maybe it will lessen their numbers and they wouldnt be such an issue.
Some people think feeding the sharks is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
@@OceansUnknownwithToddKortte Ironic but true. Some really awful things are praised as delicacies. I tried snake wine once. I had an iodine taste in my mouth for hours and it was detestable, yet it is praised as a delicacy.
I think this is awesome lionfish are an vase of species and this is all the humans fault. We need to train other animals to eat them. So we can protect the ecosystem with other fish on the hunt.
I'm originally from Florida, so yes and no. It's acceptable for Trigger fish to be habituated to eating lionfish. Trigger fish have strong sharp human-like teeth, and can easily tear up lionfish. Trigger fish seem to be resistant to lionfish fin venom also. So as long as the reef fish are resistant or immune to lionfish fin venom, then habituating them to eat lionfish is a good thing. Sharks, not so much. It would be better if sharks naturally learned to eat lionfish. When divers feed fish to sharks, the sharks tend to habituate, to being fed by the divers, and see divers and swimmers as food sources. So avoid feeding lionfish to sharks and barracuda on spears. Spear the lionfish, expelled the lionfish from the spear, and let it float. Let the predatory fish choose the wounded or dead lionfish naturally... don't fed it to them on the spear.
Feeding sharks and Grouper change the behavior to the point where they see divers as an opportunity for food. Some think feeding the sharks is not teaching them to hunt and eat the fish.
@@OceansUnknownwithToddKortte Hey before man what was their nature and what happened 2 time's before man came extermination of a lot of animal's yet look earth is still here life is still here nature can take care of itself just need's sometime to do it
This might be a mankind and nature must work together scenario. Every tool in the tool box must be used. Dont give a rats ass about ethics or what not. If you want the reef fish saved, measures must be made.

@@randomname1251 Agree and they are supposedly good to eat too.
When he told the grouper at 0:47 it was too small I absolutely died XD
Yeah the larger grouper don't have much of a problem eating the Lionfish.
Our lionfish are quite rare, and they are eaten by both sharks and our giant Javanese Moray eels. These are resident in Mauritius. Both have poisoned flesh as a result and are not eaten locally
Interesting! Thank you for sharing.
The Queen Trigger, my favorite aquarium pet I've ever had. They are voracious eaters. The one in this video is huge. Thanks so much for this video it's been a long time since I've seen one!
Are they difficult to keep alive in a tank? Do they show any aggressive behavior?
@OceansUnknownwithToddKortte I had mine a long time ago she was tiny the size of a quarter. I lost her after hurricane Andrew. We had no power for a long time. She would bite my finger and would not let go. So tiny yet so aggressive. She would eat everything I gave her, she especially loved shrimp. I've never forgotten that little beast. She had quite the personality. Some people say triggers are much like dogs.
WOW! Thats crazy. Thanks for sharing.
I like how that one fish patiently waited for its lionfish meal
They weren't debating about killing rats during a plague...
hahahaha
We can't answer your question. What happened to the grouper did the spiks injure it?
The trigger fish nibbled at the exposed flesh could it eat a live lion fish defending itself? Have they started discouraging people feeding them to sharks because they die.(Years ago that might have been thought of as a bonos).
A fish will always investigate a potencial meal but they don't know the danger an invasive fish offers.
The Grouper left the scene. The Grouper is too small, it will eat the Lionfish when it gets older.
The Triggerfish will not eat the Lionfish whole. Like you mentioned, it knew to look for the exposed flesh.
Sharks eat the Lionfish in the Red Sea.
The main reason lion fish are a problem isnt that they are toxic its that they are great at hunting, many fish have spines so most predators have ways of getting around them the main issue is lionfish look pretty unique so a lot of predators dont have that instinct to go after them like they do other fish.
Lionfish are wiping out small fish not big ones.
Not enough sarkies left here, but interestingly still normal levels of lionfish@@OceansUnknownwithToddKortte
Assume you already know triggerfish feed on other spiny venomous creatures like the queen of thorns starfish and urchins, so if any predator is going to figure out how to get past the lionfish's defenses, triggerfish already have some of the skills
Good point. Yeah triggerfish are pretty aggressive. Do you think they will start to hunt and kill Lionfish on their own?
Lionfish are more capable of evading attacks and fighting back than the triggerfish's other prey with venomous spines, so might be tough, but not out of the realm of possibility.
I find it so bizzare when saying 2017, followed by "back then"... In my head I'm like, that wasn't that doesn't feel like 7 years ago. Time is moving too fast.
Right? I was thinking the same thing when I put this together.
@@OceansUnknownwithToddKorttesame
The thing is that in order to teach the predators how to hunt lionfish, you have to actually introduce them first. They won't know they're edible if you don't give the lionfish to them to taste.
Yes very true. We will see in the future what the outcome is on the reefs throughout the Caribbean sea.
„The triggerfish is so beautiful“
It has a face only a mother could love lmao
Yeah the markings are nice on this fish!
May I ask: how come the poisonous needles/spines from the lionfish have NO effect on the bigger fish? Thank U.
1:46 it clearly had an effect on that fish
Maybe like a wasp or bee sting. Its hurts but its not deadly.
Larger fish and sharks can handle the venom in the spines.
I just assumed that triggerfish which eat sea urchins in wild would have no problem with lionfish that has even milder spines.
Makes sense
This is not controversial at all, the lionfish is an invasive species in the Atlantic ocean and can we get sharks, groupers, triggerfish or any other native predator to see them as food so much the better, because the lionfish is destroying the fry/small species of native coral fish at an alarming rate and fish are better and more efficient hunters both considering time, money than divers ofc it is good with the divers too but that is a losing battle since lionfish reproduce much faster than all of the professional divers put together.
Good comment, thanks for sharing!
I think all of this is excellent, both with the sharks and with the triggerfish. Perhaps that grouper was a better too small or got some spine from the speared lionfish. Fish are turning out to be smarter than we knew and there are an increasing number of examples of different species, even different phyla (like gobies and shrimp) working together for safety or hunting. Like with ravens - which can find carcasses they cannot open - transferring their cooperative behavior from wolves to human hunters, these fish are highly motivated to learn a new behavior that gets them food.
Awesome comment! Thank you for writing this!
Do we follow the groupers and sharks to make sure eating the lionfish doesn't harm them later?
Thats a good question. I don't know anyone that has.
Hi I think it’s great teaching these fish that they can actually eat the lion fish since it’s an invasive species , then they can help defend the reef against the lion fish 🙂👍❤️🇦🇺
Hopefully it works.
I just got basic PADI certified, and my first couple of dives were AMAZING! I’d really like to get lion fish certified and go on some hunting dives
Welcome to the dive club! Hope you have lots of fun dives ahead of you!
@@OceansUnknownwithToddKortte thanks! The dive instructor said it would be addicting, and I guess he was right! Can’t wait to dive again 😊
isnt it obvious the grouper tried eating it whole, the lion fish has spines aint gunna work so well is it
It should be obvious lol. Hindsight is 20/20
Larger Grouper don't have a problem eating the fish, I think this one was just too small.
This Grouper was too small. When it gets bigger it will eat the Lionfish.
I understand the reluctance by many to "encourage" spear fishing divers to feed the non-native Lionfish to various native fish species.
The worry here being behavioral alteration in the fish in the form of habituation.
Most wildlife scientists would discourage this activity because individual fish may then associate "food" to "diver," altering the fish's behaviour around other humans coming into that environment.
Loss of natural fear of humans may then result in injury or death at the hands of unscrupulous humans who would then bait habituated fish closer in for an easy kill (because humans just can't resist cheating).
I did have a concern that fish attempting to eat the lionfish might be accidentally injected by a venomous spine in the first attempts to take the Lionfish from the divers.
There is, as the narrator alludes, a learning curve for native species to learn how to successfully kill and then disarm non-native species like Lionfish.
My own observations with Great blue heron catching, repositioning, and breaking the venomous spines off Plecostemus before consuming the fish might be insightful here.
I'm not convinced that spear fishing divers are actually teaching native fish to hunt and consume Lionfish simply by offering them dead Lionfish to eat.
Rather, I suspect that, at least initially, it's just limited to habituation of the fish chosing to respond to a food cue.
Clearly, an experiment is required to tease out whether this hypothesis can be supported or debunked, with replication necessary for a definitive answer.
Anyone game for that?
All good points!
@@OceansUnknownwithToddKortteWanting to expand dialog and understanding to protect the ecosystems ❤
I feel like we wouldn't bat an eye if fish were taking the dead lionfish from another animal. I think as long as the predators aren't associating humans as food, or becoming dependent on humans for food, I don't see why anyone should worry. In the end if some of the higher level predators start associating the lionfish as a food source it will help the reefs in the long term. I don't normally advocate killing an animal for no reason and honestly it's not the lionfishes fault it is there, it's humans fault, but they do so much damage to the reef they can't be left alone. I feel bad for the thousands upon thousands of lionfish killed but it's less of a threat then to lose the entire reef's ecosystem.
Thank you for leaving this comment! Well said.
does the shark and other fish not react to the venom from the lionfish?
The sharks and bigger fish can tolerate the venom.
Doesn't surprise me, a Trigger will eat anything..... seriously though, one of almost all species of Triggerfish favorite things to eat are sea urchins, which have lots of spines... I would guess that it is associated the spines of the lion fish with the spines on an urchin
Good point on the sea urchin!
Looks like its Pterois Volitans Lionfish we are seeing. That was either a pretty small lionfish or a huge trigger.
This was shot in Cuba. The lionfish was on the smaller side.
when sharks eat up a lionfish, do they ever get stuck by the barbs internally?
Sharks and large fish can handle the spines.
Don't they get hurt by the poison barbs ?
Ths fish know to stay away from the barbs.
Avid lionfish hunter here. It’s not a good idea to feed wildlife. From eels to snappers, groupers and sharks that all of the sudden only follow divers, to more stressful scenarios where you have to stop hunting because there’s a problem from these practices. Today, even Florida salt water anglers that take tourists out fishing are reporting incidence in sharks and other larger pelagic fish attacking a fish on the line while the angler attempts to land the fish. The norm now is for a portion of the fish to have a chunk eaten off already before it’s out of the water. This isn’t normal behavior and it’s likely a result of a learned behavior associated with feeding. Just one example of why experts are correct when they recommend not feeding wildlife. My 2 cents. Cheers!!!
Forgot to mention. I recommend using a hard plastic container to keep your lionfish catch. There are many options out there. Zookeeper is one of the best. Hope this helps. Cheers!
Yes this is so true. I plan on making a video on the same reefs in Belize comparing 2014 to 2022. You can see a significant difference in the behavior between those 2 years I have on video. Its a night and day difference.
Oh yeah the zookeepers are great! Can you tell us all how good the lionfish is to eat? I have never tried one, but I have heard they are really good.
Could be running out of decent food to catch, so maybe it is taking advantage of the spear fishing.
Also, many people think fish stay in one location forever, it is possible this trigger fish hunts along the coast and stays near fishermen and divers for this reason?
Maybe even had a diver feed it once, so it learned the tiger fish is eatable and remembers the divers give out free easy meals.
Great comment! Thanks for writing this. I hope a lot of people read this.
Excellent educational video.
Glad it was helpful!
I've fed sea urchins to fish skin diving in Jamaica & Grenada the people in soubise eat the sea urchins roasted & call it sea eggs
Yeah fish really like the sea urchins huh?!
@@OceansUnknownwithToddKortte fish like any kind of chum
Yeah true, even like dolphin and whale poop.
Is the shark and fish immune to the lion fish poison?
Larger fish and sharks can handle the venom from the Lionfish.
Is the consensus not to feed the fish now?
Some think feeding the sharks is only damaging the behavior. Shark now look to divers for a free handout, and the sharks are not hunting the lionfish on their own.
Does the spines hurt them
The fish know to stay away from the spines. That is where the venom is.
The grouper won't, eat it because it would have to eat the poisonous barbs when it swallows it whole, but the trigger fish can just rip it apart and avoid the barbs
Larger grouper will eat the Lionfish. I think this one was too small.
Could it be that they know that the lion fish is dead and therefore being exposed itself to getting stung?
Yes that is part of it. The trigger also knows to look for the exposed flesh. They feed a lot of shark in this area of Cuba. Maybe the trigger learned to follow the divers?
Very interesting. Educational on all levels.
I always thought trigger fish just chewed on corral
Parrotfish chew on the coral. Or really the algae on the coral.
@@OceansUnknownwithToddKortte never realise they’d eat meat.
Doesn't it has poisonous spikes? I don't think it's a good idea
Yes the spines have venom. The triggerfish is looking for the flesh part.
Unnecessary trolley problem, they are not suppose to be here in first place.
yes its unfortunate. The lionfish is such a gorgeous fish, but it destroyed the Caribbean.
You say this is a controversal practice, but you don't say why. Maybe you could explain a bit more about who frowns on it and why
It teaches sharks to associate divers with food, and some believe the sharks are not hunting the Lionfish on their own. The sharks are not circling divers on the reefs in Belize to see if you are spearing Lionfish. This did not happen 8 years ago. It makes for fun diving to see the sharks, so that is good for tourism. But some people think we are changing too much with the behavior of sharks by feeding the Lionfish to the sharks.
Since lion fish are apparently good eating, it might be worth trying to push for a bounty program at a level that encourages commercial diving and harvesting operations. Take the pressure off other species commonly targeted for the dinner table.
Lionfish should be marketed as a luxury item for the weathy. Its costly to catch the fish, so the high market price would market well.
Triggerfish in general just doesn't give a *hit. There's not many other fish that'll mess around with a Trigger.
Yeah right?! They are pretty tough fish!
I still find it fascinating that an animal can be protected and endangered in one area and actively hunted in another.
I understand why, still, i find it fascinating thiugh.
Yeah good point!
My wife I spent years snorkeling in the Bahamas. We were on the island of Eleuthera, at a place called Raibow Bay. One of the most beautiful locations on the planet. Not exaggerating. Look it up. We snorkeled way out. Long story short - and it's a long story - my wife was attacked by a reef shark there. It did a figure 8 "threat dance" before attacking her and unfortunately, we didn't understand what was happening. We were not spear fishing and we didn't know spear fishing had become so common. As my wife was recovering, the locals explained that reef sharks around the island now hunt down humans because they expect to be fed lionfish from spear fishers. Several fishers get bit just from carrying the pole - as the reef sharks now associate a free meal with the pole. Sadly, my wife will never snorkel again. Sometimes she still wakes up screaming from nightmares. We had to find new hobbies. I'm not passing judgement, the lionfish need to be dealt with. But just sharing our experience.
The same is happening in the Caribbean. Sharks follow divers and look for free handouts...Lionfish kills on the end of a spear.
Don't lionfish have poisonous barbs along their spine?
They don't care. They seem to know where to bite.
Yes that is why most fish do not eat the Lionfish. The Lionfish eats all the fish. The math is upside down, that is why the Eco-system is all mess up in the Caribbean. The fish know not to eat the spines.
Yeah they know not to touch the spines. They are looking for the white meat from where the spear hit the fish.
Looks more like the triggers were mostly just being territorial.
Yeah maybe part of what is going on here. Maybe the trigger is fed up with the Lionfish and it is some kind of territorial revenge?
The trigger fish is very territorial, it can even kill the most venomous starfish, the queen of thorns
Yeah tough fish for sure
But aren't lionfish venomous? Is it safe to feed it to other fish?
the spines are, the fish isn't. Some of those sharks, eels, and other fish seem to be able to eat the lionfish without being hurt by the spines poke. I think the toxin it uses just causes pain, it won't actually kill anything past a certain size.
It might burn a little coming out. LOL Like really hot hot sauce!
Larger fish like sharks and Grouper can handle the venom.
Eating venom is harmless. Eating poison is not.
Great video
Glad you enjoyed it.
I dont think its a problem, its not like there are enough divers to support the fish and it just shows them a new food source, fish are smarter then people realize. Trigger fish are actually quite capable of learning and if it realizes it can catch lionfish it might start going for them, they can be surprisingly predatory.
Good comment! Thanks for sharing!
As long as it does not involve the introduction of another invasive species to combat the Lionfish I do not object.
Yeah, we don't need another invasive species.
Seems like Lion Fish are always shown as an invasive species, so where exactly are they native from?
Red Sea and I thin the Indio Pacific. Grouper and Sharks already know to eat them in those areas.
i dont think its a problem, you help animals to adapt to a new threat, there is no problem with that.
Good point, thanks for sharing!
What the hell what about the spines
You can see the Triggerfish avoid the spines.
@@OceansUnknownwithToddKortte im still terrified. Imagine that going through the roof of your mouth. Even as a fish that would suck.
What controversy? It is invasive with no known enemies. Teach the sharks and anything else that will irradicate the threat.
Some think feeding the sharks is changing shark behavior too much and the sharks are not hunting the Lionfish on their own.
Triggerfish is general are just very opportunistic feeders and will eat just about anything that looks like an easy meal.
Yeah they are pretty aggressive huh?!
Eventually the other fish will realize/learn to eat the lionfish. They just need time. Nature has a way of self-balancing.
That's true, but with all the other environmental changes, like coral bleaching, many species are not able to adapt fast enough. It's too much all at once.
@@joshuacook2 Too much for what? For all species to adapt? Of course. Nature is competitive, and if you can't adapt fast enough, your form stops being alive. Other life evolves to take your place. I'll bet sharks are going to be fine, they have a pretty good record.
How do you protect the predatory fish from the venomous spines? Aren’t they still venomous even when the lion fish is freshly killed?
I know I would never trust anyone who offered me a salad made of fresh cut stinging nettles.
Larger fish and sharks can handle the venom in the spines.
From personal experience, enuring sharks, or any other potentially aggressive fish, to take lionfish from a spear can have rather stark unintended consequences…
My teammates and I hunt lionfish regularly, at depths between 40 and 60 meters, racking up significant decompression obligations. At one point a few years back, we had to abandon a favourite hunting spot as we were being harassed, constantly, by a 2m nurse shark that we believe had learned to associate not only divers, but yellow pole spears too, with free meals. Fending off it’s continual advances for 40 minutes grew not only tiresome, but put the team at risk of violating the decompression schedule. That is a dangerous situation… We’ve recently had a few divers have unnerving encounters with sizeable free swimming green morays seemingly looking for handouts… Again, no bueno…
I am of them mind that divers should lookout for the reef ecosystem by hunting as many lionfish as possible, but please do so in a responsible way and take your haul home to eat… They are great for ceviche and make really nice fish-n-chips!
Yes, you are so right about the yellow pole. Some grouper look for the diver with the yellow spear.
Thank you for this comment and the information. Do you notice more lionfish at deeper depths than at recreational dive limits?
@@OceansUnknownwithToddKortte - Where I’m at, Utila Honduras, the shallower reefs are heavily hunted so that segment of the lionfish population seems to be fairly in check. Since there’s only a handful of divers that regularly tech dive here, it’s easier to get a significant haul down deep. A few years back we participated in a research project where the goal was to sample and age the lionfish population from the shallows down to 100m depths to see if there a correlation between depth and age and/or size - the theory being tested that lionfish tend to migrate downward as the mature. It seems there is an aggregation level, here, on the sand shelf that surrounds the island at depths between 35m to 70m. Below that, on the deep walls, they’re harder to find… Though, our deepest sighting was a bit too deep to be hunting at around 130m!
Ive been diving in Honduras. I know what you mean. Our dive master speared some lionfish for the resort to make ceviche.
Why don't you think the trigger fish could reasonably be expected to associate you, a large mammal, with access to feed? Time aside, the fish's brain could recognize a behavioral scheme of predation anyway, and would not even need to know anything about you necessarily to see the lionfish is incapacitated anyway.
Some people think feeding the sharks is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
Familiarity dulls the fear. The more they see them the less they fear them and see them as a food they should learn to predate.
Good point!
I purchased a lion fish and it died in two days 😢… never again
Oh wow, why do you think it died? How much does a Lionfish cost?
@@OceansUnknownwithToddKortte I probably payed too much . 100 bucks. Not sure why it died looked healthy and was eating
I would imagine Lionfish being a popular fish in the aquarium trade.
I always thought groupers were the most intelligent fish. I’ve seen groupers hunt and corner lion fish. Surprised you see this behavior on a trigger fish. It is even aware of its spines. Amazing
Yeah grouper will show you where the lionfish is so you can spear them.
I haven't seen trout in Walmart for a long time. If the Lion fish tastes anything like trout I'm in.
I heard they are really good eating
The problem is all those fish will come to unsuspecting divers begging for foods, some of them can be aggressive
True. Some people think feeding the sharks and fish is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
Astounding to see that sharks and queen triggerfish are able to eat lionfish without consequences of the venom.
The sharks are big enough to not be bothered by the venom.
Would next crisis be Lionfish extinction crisis? once other fish learn that it is ok to eat lionfish
I don't think it would reach that level.
I feel like the difference in the way the triggerfish and grouper eat their food has a lot to do with why one ate it and the other did not.
Triggerfish have enough teeth and a small enough mouth that allows them to peck and take small niblets at a time. This combined with the fact that it can probably detect the fish is now dead and spines disarmed, it has no problem going after it. However, you can still see it swimming backwards sometimes to still keep the spines at bay and have access to the meaty bits. Like it still knows it's a threat, just not a live one.
The grouper doesn't have the teeth necessary to take those small niblets, if I'm not mistaken it's basically a vacuum eater and has a handful of teeth to hold onto the fish, but not chunk bits off. So to the grouper, those spines attached to the carcass still pose a huge threat.
That's my take on it anyways :). Solid footage though, that Triggerfish is beautiful.
Good comment. Thank you!
The Grouper was too young to eat a lionfish. The larger Grouper eat them whole with no problem.
Fish are learning divers = slot machines with high payout.
They are eatting what the divers give them, because they see them as safe, like how when a aquarium fish learns you, they always swim to the glass when they see you because they know its time for feeding.
Eventually they will learn to eat the lionfish naturally, but its most definitely due to the divers influence.
But in reef tanks, one of the most annoying thing is getting your fish to eat what you want them to eat. Sometimes it happens over time with routine, other times the fish will die before it eats something its not native to. This is why most of us quarintine the fish not just for observation, but to also start training it to eat the foods you want them to eat.
As for is it OK? absolutely... There is no otherway to get rid of an invasive species other then using a natual species to hunt it out of exinction before the other members of the ecosystem falls off due to it.
Really interesting points you made about the aquarium fish. Thank you for sharing!
Second dive vid from Cuba ive seen in the past week or so. Maybe it's a sign 😂
It's a must see spot to dive. Jardines De Le Reina or Gardens of the Queen. Well preserved Eco-system.
@@OceansUnknownwithToddKortte Can you recommend the best city for a diving home base? Do you have to fly from USA to Havana, or are there direct flights from the USA to the diving bases?
Had a friend that had a lionfish and a parrot fish in the same tank. The parrot ate the lion.
Oh wow that is crazy!
Those spines are a deterrent even after being speared.
Yep sure are!
Are those sharks going to regret eating that?
No they can handle it.
@@OceansUnknownwithToddKortte well, good for them, bad for lion fish 😅
The invasive fish needs to be kept under control. The idea that it might be a bad habit to form looking for food from humans, but the lionfish is a human-related problem too.
That triggerfish was beautiful.
Yeah the triggerfish is definitely beautiful. Such a cool fish.
Corral crunchers may have enough armor on their mouth.
It went for the exposed flesh and stayed away from the spines.
@@OceansUnknownwithToddKortte A pouting mouth may be advantageous over a gaping maw in this case. Fishes are smart in their own ways. Urchins are well armored but they have predators. I will watch again and pay attention to its line of attack. :) Ah it may be the dorsal spikes. They get stung on their palate. The trigger fish shred and nibbles but avoids the dorsal spikes.
it’s freeding frenzy all over again
Yep sure is.
if they are invasive i see no problem with either keeping it or feeding other fish on the reef with it. If you teach the other reef fish to eat the lionfish then maybe it will lessen their numbers and they wouldnt be such an issue.
Some people think feeding the sharks is only damaging their behavior. Sharks now look to divers for a free handout, and the sharks are not hunting the lionfish on their own. The fish and sharks need to hunt and eat the Lionfish or it will be the only fish left on the reef.
Perhaps the trigger fish saw an oppotunity for revenge, knowing that the lion fish is a predator.
Setting up exotic table for native fish serves Gaia right.
The lionfish should be marketed as a high end expensive fish, attracting the wealthy and creating a demand.
@@OceansUnknownwithToddKortte Ironic but true. Some really awful things are praised as delicacies. I tried snake wine once. I had an iodine taste in my mouth for hours and it was detestable, yet it is praised as a delicacy.
Give a fish a fish, and it eats for the day. Teach a fish to fish and it'll hunt down invasives.
🐟 🐠 🐡
Oh very clever comment!!! I have hundreds of comments on my instagram video of this triggerfish and nobody thought of this comment! Nice job!
Good idea to get rid of an invasive species.
We won't will this battle. The Lionfish are taking over the deep water.
I think this is awesome lionfish are an vase of species and this is all the humans fault. We need to train other animals to eat them. So we can protect the ecosystem with other fish on the hunt.
Hopefully the other fish will learn to eat the Lionfish. If not, it till only be lionfish on the reefs in the Caribbean Sea.
I'm originally from Florida, so yes and no. It's acceptable for Trigger fish to be habituated to eating lionfish. Trigger fish have strong sharp human-like teeth, and can easily tear up lionfish. Trigger fish seem to be resistant to lionfish fin venom also.
So as long as the reef fish are resistant or immune to lionfish fin venom, then habituating them to eat lionfish is a good thing.
Sharks, not so much. It would be better if sharks naturally learned to eat lionfish. When divers feed fish to sharks, the sharks tend to habituate, to being fed by the divers, and see divers and swimmers as food sources.
So avoid feeding lionfish to sharks and barracuda on spears. Spear the lionfish, expelled the lionfish from the spear, and let it float. Let the predatory fish choose the wounded or dead lionfish naturally... don't fed it to them on the spear.
All good points! Thank you for sharing!
Before this video the only fish I saw eat a lionfish was a grouper
Thats what I was thinking when I was shooting this video in Cuba.
I really don't see how this could be controversial!
Feeding sharks and Grouper change the behavior to the point where they see divers as an opportunity for food. Some think feeding the sharks is not teaching them to hunt and eat the fish.

pestification of life on full display
Yep sure is.
I don't see any ethical issue with teaching our fellow creatures to eat an invasive species.
Good point. They need to learn to eat it, or the Lionfish will be the only fish left on the reef.

This might be a mankind and nature must work together scenario. Every tool in the tool box must be used. Dont give a rats ass about ethics or what not. If you want the reef fish saved, measures must be made.
Well said! Thank you for your opinion.
You can't have human divers to all the work. It would be better if local predators can help keep the lionfish population under control.
Yes we need the predators to take over.
