Good! Leave it. That ecosystem is undergoing a restorative cycle. By the end of the season there should be a productive burst of wildlife in those place that humans normally interfere with and pollute destructively. Initially some animals will die (leatherback turtle hatchlings), but natural selection will play out without human interference.

Ciguatera poisoning , high levels of bacteria that live in the seaweed , uncertain time of death for some of the fishes

Allot of those fishes are Balahoo, great bait and can be sold very easily as it’s always in high demand for game fishing .

Ocean flora/algae contributes more to atmospheric O2 than the forests.

This is probably the earth's "autoimmune" response to increased Co2 levels

We er figure out what to do with sargassum yet?

A twig is worthless, but a warehouse of lumber can be sold for construction.
A cup of water is worthless, but you can sell a reservoir to a small village.
A Brick is worthless, but you can sell a couple thousand to someone to build a house.

If we have so much of it, we can surely do something with it.

It is a blessing in disguise.

This event if it hits us seriously may very well restrict income generating possibilities, recreational activities and even many folks ability in seaside communities to have a pleasant easter season.
Tobago windward side, the last time this was bad was a total mess with clean-up activities severely stretching the THA capability to cope.
Folks who have booked vacation break have to keep their fingers crossed.

Apparently it's not that difficult to process it to remove the Arsenic and use it as an inexhaustible supply for animal feed at least. It's also edible for humans as a seaweed after processing.


https://europepmc.org/article/MED/34953872

Arsenic removal from the popular edible seaweed Sargassum fusiforme by sequential processing involving hot water, citric acid, and fermentation.

Abstract

Higher quantities of arsenic (As) in Sargassum fusiforme limit its use as a food ingredient. The present study aimed to reduce As in S. fusiforme using sequential processing involving hot water, citric acid, and fermentation. The As content in S. fusiforme of 76.18 mg/kg was reduced to 30.47 mg/kg and 24.45 mg/kg using hot water and citric acid processing, respectively.

However, the As content in S. fusiforme was reduced to 9.09 mg/kg by sequential processing with hot water and citric acid.

Using response surface methodology, optimal processing conditions for S. fusiforme were determined to be treatment with hot water at 60 °C for 120 min followed by treatment with 0.4% citric acid.

To further reduce the As content, the processed S. fusiforme was fermented by Lactobacillus rhamnosus, and the As content was further reduced to 1.64 mg/kg. In addition, the levels of organic acids and amino acids in S. fusiforme pre- and post-fermentation were significantly altered. These results indicated that the As content in S. fusiforme could be effectively reduced using the sequential processing with hot water, citric acid, and L. rhamnosus fermentation, and the organic acid and amino acid levels were significantly altered by L. rhamnosus fermentation.

Record long seaweed is stretching from Africa, across the Atlantic Ocean, into the Caribbean and Gulf of Mexico. It is twice as long as the USA... 5000 miles long, or 8000 km!
