Sargassum crisis: Fishermen in Martinique develop solutions
Вставка
- Опубліковано 27 сер 2024
- A giant blob of seaweed in the Atlantic is discouraging tourists and threatening communities on the French Caribbean island of Martinique.
Mounds of free-floating sargassum wash up on beaches, and as it rots, it releases toxic gases.
Fishermen and entrepreneurs have taken matters into their own hands, coming up with a solution.

#Sargassum
#Martinique
I have worked on seaweed for many years and people are yet to realise its importance. This particular seaweed can be used for enhancing fertilisers, fish meals, for paper production, cups etc... Nevertheless, we should also realise that seaweed has vital ecological functions to the seawater quality and a habitat for fish and other micro and macro marine organisms.
I thought me the same like you say ..on top is flushing on the beach and make new land ,,over many years humans just don't understand the have to life with the nature together ..
True... but exaggerated amount of something good will always have the opposite effect. Looks like plenty to find good use of it.
You have it all then
It works as a pesticide to. But too much is annoying
seaweed has its uses but this is plauge level problematic. i do wonder if the waters are cooler where it resides due to it blocking the suns rays.
I have lived in South Florida all my life and this would occasionally be a minor nuisance. Now it’s a major problem.
Sargassum hyperbloom caused by nutrients that enter Gulf Stream currents via polluted rivers globally.
It’s not commonly used for fertilizer because it contains toxins and heavy metals which carry over to food.
While sargasso is vital for a multitude of species, and over abundance can cause massive damage to marine seabeds with grass or coral.If the light cannot penetrate because of a blanket of rotting algae, the grass and coral begin to die.
The sargasso itself is not new, the amount we are seeing is not normal.
Because it has toxins we should leave it in the ocean. That's just stupid
Sargassum is widely regarded as a bio-fertiliser in agriculture. This nutrient-dense macroalgae is rich in minerals, water soluble polysaccharides and phenolic compounds which collectively enhance soil health, quality, productivity and enzymatic activities.
Your forgetting the high salt load which needs to be removed first for any practical use.
@@MrSeachaser175 He is just running on without thinking.
You are correct. We purchase dry kelp meal for the farm and it is by far the most expensive anendment we buy.
It can be a good soil amendment if they first process it to remove the arsenic
It has high levels of heavy metals which will contaminate crops which are used for animal or human food. It likely shouldn't even be used for things which aren't food crops because it eventually will move to those areas. Cotton crop pests were treated at one time with arsenic and if the fields are going to be used for food crops, there is a problem.
The one major problem with Sargassum sea weed it is loaded with salt, so unless you are prepared to wash the salt out it can’t be used for anything especially fertilizer as the salt is deadly to plants.
You are misinform about the types of salt that is contained in seaweed
@@shaneildyall5498 as a professional yacht captain for the last 50 years I know all about seawater so don’t you tell me that I’m misinformed, if anything you are.
What these fishermen are doing is outstanding. That adaptation of their vessels is amazing, I hope the seaweed they collect will end up used in something meaningful such as fertilizer or other use.
first thing it can be used for is producing Biogas. and as a byproduct we get fertilizer.
I live in the Caribbean and can't remember there ever this problem before 2011. It ruins all the beaches on the East coasts of the islands
Mate, I live in Dominica Republic, same problem as in Martinique, its simple, its the best fertilizer and cattle fodder, abd easy to handle and make ready to use. Every year take a tractor with two large carriages to bring on about 2 metric tonnes of the stuff from thr beaches up to our coffee farm, there we compost it with coffee mulch residue and make fertilizer for the plantation.
tons of arsenic and heavy metals are concentrated in sargassum, at levels way higher than what is normally allowed in Animal fodder
A frequent visitor to your country and that stuff is horrible for tourism. Especially Punta Cana. I now visit La Romana as it’s virtually no sea weed.
@@theknow7557 well theres nothing human can do and its not always sargassum i live in punta cana and as we speak the beaches here are clean clean
I can’t imagine what could go wrong when Florida has lakes of fertilizer that leak into the Atlantic.
There are commercial crops that are salt tolerant if you can keep it reasonable. Wash it in river water. That is a lot of nutrient that wouldn't require much fuel to turn into lots of high value fertilizer. Sun dried and baled for processing.
I love the new technology to get the seaweed collected, but businesses should get together to combat it before it gets to their shore so it doesn’t destroy their economy. Very sad indeed 😞
... they don't have the money. That's why their Government needs to do that, collect it, and resell it as a bio resource for agricultural purposes, or into another renewable resource 🤔
Collect and compost it using the very efficient worm compost method to create nutritious black soil. Use the black soil to grow vegetables, fruit and berries.
You could also feed it into a biogas plant and generate energy in the form of gas or electricity.
There are plenty of seaweed products origin from sargassum , ascofol, giant kelp etc selling so expansive in the fertilizer market. Couldn't believe , now it is free outside your door step
The cause doesn't seem to enter into any reports about it. Increased amounts of nitrogen from treated sewage being pumped into rivers and oceans. Human waste being dumped into the sea by cruse ships and small crafts with no restriction except being a certain distance from shore. The increased nitrogen levels are the cause of the huge increase of sargassum.
Cruise ships do not dump human waste.
I seen a story from a India tech company making biodegradable plastics and glue from seaweed . They were growing it and unsure if this can be used in it's place but if this is a recurring problem could be worth finding out.
I don´t think we should be transporting it to other ocean basins as there´s a risk it will spread worldwide. Best to use locally sourced seaweeds to transform into usable, beneficial products.
When someone finds something very useful for it, a financial boon, then there wont be enough vessels to scoop it up.
Collect them > Spray enzymes/bacteria > Bury them > Wait for 10-20yrs > Fuel > Profit
Collect it grind it, ferment it capture the gas then refine it sold it. The pulp dry it make it into fertilizer
very valuable natural fertilizer ! its a gift , use it for growing food .
I watched another video about this problem with this type of sargassum, and one person decided to make use of it. He developed a system of mixing sargassum with other products like lime or cement of some sort, and is manufacturing bricks for home building.
This is basically free organic fertilizer!
That's nothing compared to the sarcasm bloom that's coming.
Oh sure, there's just sooo much sarcasm on UA-cam. Not a chance, pal.
lol
What to do with the arsenic in the sargassum? If that can be ameliorated, the sargassum can be used for bricks & other beneficial purposes.
I bet you a dollar to a dime those fisherman are dumping the seaweed back into the sea downwind from their tiny island.
That would be stupid.
Seaweed is a great source of minerals and useful phytochemicals. Seaweed is pure gold for agriculture. This stuff is very good and simple to ferment into a mineral supplement.
A 50 pound bag of dry kelp meal retails for over $100.
What about the salt ?
@@CommercialVehicle Any place that has a river that runs into the sea can use the river water to rinse the salt before processing. It's not complicated.
Does anyone see the big picture? This is not normal and is caused by a serious environmental change. Both ocean temperature elevation combined with human release of farming fertilizer draining into rivers are feeding the bloom. Humanity can’t regulate itself and thus is disrupting the natural order. Sad.
Seaweed in sea is not normal? How about look at how media distorts knowledge?
If not used for raw material, the Sargassum could sequester carbon if buried in salt and make money
This is not Martinique. It is Marie-Galante from Guadeloupe Islands
Isn't there a shortage if fertilizer?
Put in the fields!!!
It can be used in beauty products, fertilizer and production of gas this has been implemented in México
Turning it into fertilizer?
too many toxins from cleaning the ocean =(
Its a blessing
I used to go the the caribbean during vacation , I cant anymore because the sargassum has gotten so bad. I stay in New Jersey the water is 72 in August and no sargassum
Mother nature. Learn to live and work with her, instead of destroying it
A man in mexico creates bricks made of sargassum and builds houses with them. He created entire business on top of the existing business of cleaning it up for hotels in mexico.
Seems to me these folks could team up with the people involved in The Ocean Cleanup project. The latter's System 3 could probably help quite a bit more than the small vessels they are using.
It can be ground up and sold in bags to be mixed with compost. It is an increadable plant food.
Regards from South Africa
They can use it for agricultural production. It is very rich and nutrition
Wonder if it could help fix radioactive sea water? And if its there to fix the pollution being put into the ocean from nearby where its seems to be a problem?
This is a great soil amendment and hopefully they can dry it and sell it to tourists for their gardens back home.
Can the seaweed be mulched into the soil… so you might have better soil for farming in the future
It can be used as fertilizer
It’s a big problem in the Caribbean
Fishermen at Martin’s definitely had to change strategies!
JD
Net and tow is what we did at the Alaska oil spill. Tow it into the passing current.
Collected on a boat. Then what happens to it?
They dump it somewhere else
Sargassum is extremely important to our pelagic fish pollution. Juvenile fish and organizims live in it, and large patches floating in deep water are great large fish attractive, which we target to catch and eat.
As expected, the news is always doom and gloom, never provide you with both sides of the matter.
Too much is damaging, do you not have a brain.
Some sargassum yes but now there’s too much that it’s affecting quality of life in the Caribbean.
Should dump it in your yard, since you like it so much. You sound like a fukn half baked nut.
Hopefully this problem will be solved.
Very sad. Hope you guys are able to get rid of the seaweed.
Who’s the Irish narrator ☘️👏🏼
very clever ❤
Caribbean people two main problems are seaweed and hurricane 🌀 😐
COMPOST IT !
Why does the audio on this video only play out of my left earphone? so irritating.
It is easy what we can use it for. it is biomas. so we can produce Biogas from it. Green energy to be used flexible. And as a biproduct we get fertilizer.
good as a fertilizer.
Could be, is not a clear definition of the cause. Corporations an gov. Know what is causing it.
use that as fertilizer
Create a pit filled with biochar, place seaweed on top, cover with mulch inoculated with oyster mushroom, cover with more mulch & dirt. You have just created tera pretta. Plant fruit & timber bearing species like bamboo, gumbo limbo, African mahogany.
Wont the salt laden seaweed kill the plants?
looks like a perfect fertilizer to me with tons of minerals... how is a bad to economy.
Is cloud seeding causing this?
I’m the past decade farmers in Brazil started using a new type of fertilizer but when it gets into the ocean it starts this
Many countries in the east coast are losing tourists because of it country’s tried convincing Brazil to stop but Brazil it basically like f all of you we won’t stop
Increase in water temperature from climate change and nutrient runoff from the agriculture industry have created conditions for super blooms.
😢in Tobago its the worst but they also use it for plant fertilizer..
Thoughtful ideas. It's hard to get attention for the new good thoughts. Thank you for covering this. Hello Elon 👋 we need your help
That's great fertilizer y'all, collect it, bill the city for it, them sell it
it's a very easy question to ask. where did all the fertilizer come from? considering as a Floridian I know that Saharan dust comes all the way across and lands in the Gulf of Mexico! I'm thinking that African dust has something to do with it. people pooping out in the desert becomes dust. 50% of the dust is fecal matter! highly nutritious for seaweed
It's more likely because of the insane amount of fertilizer that gets into rivers and then to the ocean.
@@PG-3462 Yup. With a significant amount of that from Florida, which is already well established has having frequent problems with algal blooms due to fertilizer runoff.
It’s actually coming from industrial 🏭 runoff
Cane be used as fertilizer
Why cant they use it for biofuel ?
If you care for an aquarium you can relate...
It should be used as fertilizer
you all cant put up a net to block them
hire locals they need the work, seriously.
With the covid pandemic and now the war in Ukraine the world fertilizer production was reduced a lot so instead of a problem i see a solution why not put this free organic fertilizer to use instead of dumping it
It’s bad in Mexico too
Its going to take a lot of bags to collect all that sea weed!!
There isother composite materials that can be made with those, look at what INDIA is doing with them
Free fertilizer
Wasn't there a big push about seaweed being healthy for you to eat where is all the vegetarians why don't they eat the stuff
been there for all time,christofer columbus described it.
indians in carabean ate it
Send me a few tons. I bet this stuff will green a lawn up quickly!
Mother Nature is WOKE
Governor DeSantis is going to ban it.
Humans release waist and co2 nature finding whay to use it and reduce it.
Turn a waste product into a recourse and yu have a twofer.
... recourse or Resource 🤔
Research if it can be turned into food for humans.
Yes it is food as well as an ecosystem! :)
@@NBflame cool
a Mexican is making bricks from it
This would be a good area for government subsidy.
Deforestation and extra nitrogen in the water.
💛
😢
Scientists don't know, yet the creator of this video blames "global warming. Just adapt people and stop promoting propaganda.
It’s nature crying for help
Just compost it
A shame
The fertilizer causing this comes from Russia.
The Sargasso Sea has been around forever. Columbus wrote about the ocean being blanketed from horizon to horizon with the weed. No "global climate warming ozone" then!
BELIZE NEEDS HELP
Another biofuel source.
Looks horrible.
And also smells horrible.
Ship it to the Sahara desert and bury it in the sand then after the climate change people will have good soil to grow a garden
The only thing the sagacity is good for is the plants that comes from Allah need to ground this guy will kill them so think about it Sadat Saline it is good for plants
