Feeding lionfish to sharks
Вставка
- Опубліковано 29 бер 2018
- A divemaster off the coast of St. Kitts spears lionfish (an invasive species in the Caribbean) and feeds them to sharks to teach them to seek out the fish as prey. The lionfish invasion is considered to be one of the most serious recent threats to Caribbean and Florida coral reef ecosystems. Culling by marine protection agencies and volunteer divers is an important element of control efforts. Adult lionfish have few identified natural predators, likely from the effectiveness of their venomous spines. Moray eels, bluespotted cornetfish, and large groupers have been observed preying on lionfish. During our diving at St. Kitts, we witnessed that sharks are also capable of preying on lionfish with no ill effects from their spines. Development of market-based approaches, which create commercial incentives for removals, has also been seen as a means to sustain control efforts. The foremost of these market approaches is the promotion of lionfish as a food item. When properly filleted, the naturally venomous fish is safe to eat. Another control method is the use of lionfish spines, fins and tails for jewelry and other decorative items. Lionfish jewelry production initiatives are underway in Belize, the Bahamas and St. Vincent and the Grenadines.

I love how they start to grasp that you’re actually giving them the fish and they don’t have to be as aggressive.
Why waste energy when you don't need to?
This is actually far more aggressive than sharks normally behave.
@@TheLastWalenta why do you think that is? A competitive kind of thing?
@@FirstFamilyCharger No. Sharks aren't competitive. They are apex predators feeding. In my hundreds of dives with sharks, they have never behaved this way. Humans are not on the menu, and in fact the bubbles divers create are an annoyance. Sharks try their best to avoid people and also these very types of situations, but simply can't help themselves with injured prey on a harpoon.
However, divers behaving this way is quite irresponsible, for reasons I posted directly to the video. I can post it here as well if you wish :)
By the way, no diver should ever do this, for a variety of reasons, including but not limited to:
1) It is dangerous for the shark. The extremely sharp harpoon poses a significant risk to an aggressively twisting shark.
2) It is dangerous for all divers that frequent the general area. The fact that you are training the sharks to associate humans with feeding inevitably leads to sharks approaching future divers with feeding expectancy and aggression. This has been proven in all oceanic environments where chumming is common, from Jupiter, Florida to Isla de Cocos in Costa Rica to Bali in Indonesia.
3) While I recognize the ecological impact of lion fish, sharks play a far bigger and more important role in ecological control. By training them to wait for their food, they stop performing their natural roles of population control on the reef.
I understand how humans got ourselves into this mess with lion fish in the Caribbean, and how we feel we can fix our way out of it. However, throughout history we have made environmental disasters worse when trying to introduce extra variables or controls.
It is generally accepted biological principle to leave natural habitats as they already are. In the case of the Caribbean, that is no longer possible. However, training the apex predator of the area to alter behavior is a disasterous idea. Human control of the population is the best regarded method until we can determine a way to prevent lion fish from spawning (introducing a genetic variant of lion fish that cannot spawn into only the affected areas, for example) or by luring only lion fish into traps.
But please, for the sake of all stakeholders involved, including humans, sharks, and the general environment, please refrain from doing this.
"GUYS I SWEAR, THE FOOD WAS GIVING ME FOOD"
😂😂😂😂😂😂
Humans aren't food.
@@mirsad96 I beg the differ 👀
Very smart. Just looked it up, and sharks, groupers, and eels are natural predators of lionfish in their native habitats. Lot more efficient than having human divers hand pick them one by one ad infinitum in perpetuity.
Baracuda can also be trained to eat them if im correct
How do the predators avoid being poisoned?
"We are trying to train the sharks to become predators to hunt and eat the lionfish"

"I like 'em off the shish kabob, thanks. More please..."
- sharks
How do you teach a fish to eat another fish that has spines? I always thought the spines were deadly to other fish.
Reef sharks, in particular Hammerheads, are generally unaffected by stuff like that. They guzzle down jellyfish and stingrays easy-peasy. Even eels are mucousy enough to chomp down some lionfish
You're actually teaching them to take fish off of the spear of someone spearfishing. If another spearfisherman is spearing some other type of fish and then all of a sudden these sharks show up, they don't know that the sharks are used to it, they may actually think the sharks are being aggressive towards them.
considering the lionfish is an invasive species that is wrecking the native fish stocks Id have to assume that the local fisherman are aware of this trying to train the Sharks and Eels to eat them to keep numbers in check.
@@exiaR2x78 It is, but what I'm saying is to kill the lionfish, then leave it , the sharks will get them on their own. Don't let them take it off the spear, where other spear divers hunting for other fish don't know and think the shark is attacking their fish they just speared.
You're absolutely correct and they don't care. Just the act of feeding sharks is completely irresponsible.
This is the most beautiful thing I have ever seen!
Are you blind then?
You don't get out much
You're a Redditor I guess
Encouraging other animals to eat the lionfish is a great way of dealing with this vermin! 😁👍👍

how can sharks eat the lionfish, if the lionfish has its spikes?
That’s one way to get rid of them
Is that a mako shark?
Yes but are they learning to eat them on their own? And why dont they eat them normally? Because they look deadly?
Thanks. Now sharks are asking me for fish every time I go for a swim
Sharks are fast!
Barracudas are eating them too, this is great shark helping eat them, as well as a few other sea creatures are trying to eat them or learn to as well.
This is a prime example of DELEGATION!
noticed many of those pest control videos about lionfish. Could somene give me please a short insight how exactly they are endangering coral reefs?
they compete with native predators, leaving them without food; they reproduce faster and due to their young not having as many predators, a much higher percentage reaches adulthood; once they are adults, lionfish are eaten by far less things (only large morays, groupers and sharks will take them); they eat a lot of native fish and crustaceans, applying pressure to their populations
They eating up everything and basically taking over (short hand)
They are an invasive species that reproduces very fast and grows to adulthood very fast while wiping out native species that keep our reefs clean and healthy. Lion fish are not beneficial and only destroy the natural balance.
They eat everything and reproduce fast then compete with native predators
Only certain things can eat them like morays, sharks and barracudas
@@British_Bastard and groupere
No natural predators: Mr. Shark, meet Mr. Lionfish. Perhaps Mother Nature will adapt.
Thought lion fish were poisonous.
Those poison spikes are ok to eat.
They are actually venomous, venom only does damage if it enters the blood stream (by being injected with a needle or fangs)
Yes but if a person tries eating them it would cut you and the venom would enter youre blood stream and give you a fuck ton of pain
@@unkownboi67is_unavailable62 True, that’s why they are teaching them to eat the lion fish safely, where the spines can’t harm them.
they be like these tacos extra spicy!
Don’t the poisonous fins affect the sharks ?
probably no because in indian ocean sharks and groupers prey naturally on lionfish,
Lionfish are an invasive species anyway
Those sharks are getting a mouthful of venom
There's no difference when sharks eating stingrays
*Tiger* Sharks VS. *Lion* Fish ..
The ULTIMATE Showdown!!!!!!!!
... those were Tigers right? Lol
No. I think they're black tip reef sharks
Would this make the sharks more aggressive toward divers in the future? Not sure but it seems like the start of a cycle where the sharks expect to be fed by humans.
I doubt sharks will be helpless and die of starvation when no divers with fish on their spears ready for them won't be around... 😁
A lot of reef sharks interact with divers, the only issue is if they see someone spearfishing in the future theyll likely expect to be feed by them. If the divers are aware of this it shouldnt be an issue they might just have to give there catch to the sharks though haha
This is awesome
The lone fish don't move too quickly so they should be easy prey for the sharks. I suppose you try the sharks to eat the lionfish they would be your first point of call for getting rid of the lionfish population
It would be just my luck to get reincarnated as a lionfish 😂😂😂😩
Sounds like a title of an anime
We’re any lion fish harmed in this video ,just asking ,lol
They have to give it for sharks to eat it from head to tail. Looks groupers attacks in lion fish
it is gonna take every diver working hard to control these rascals - here is my contribution to the effort in Cayman - ua-cam.com/video/YLAeeYwfcl4/v-deo.html - feeding snapper and ua-cam.com/video/6_BdtOFi_mg/v-deo.html - Feeding Moray

How? like how these sharks r not attacking one of em, have they done something or what's going on?
Shark in real life is differrent that you saw on the tv, just 3 kind shark that aggresive, great white, bull, tiger.
talk about acid reflux!
Have the sharks learnt to hunt these meniscus??
i wonder the same and also if the fish survive eating the lionfish, because of the spikes
meniscus? ;D Do you even English? ;D ;D ;D
@@Blei1986 sharks can eat lionfish no problem
They just get used to eating them.
Lionfish usually stay still because they can’t travel long distance and don’t think of anything as a thret
Poor lionfish😭😭😭
Invasive lionfish
Estas son las personas que han enseñado a los tiburones a comer personas. Que mala enseñanza

Turns out a bunch of sharks died great job
These poor sharks will probably die later on.
All animals “die later”. Lion fish are a natural prey of sharks.
Lionfish don’t harm sharks
@@British_Bastard How do you know?
@@treich1234 when it’s in the system it’s fine, I also think they don’t get effected by toxins released
We are going to end up making sharks fat lazy sea creatures that end up begging for food from us like my Chihuahua. They’ll be following divers around and nipping at each other cause they don’t want to share.
What a drama queen. It would take an entire army of divers doing this for years and years and years for that to actually happen.
@@FirstFamilyCharger well he did say he owns a chihuahua so it makes sense for him to be a drama queen
