[Coral-List] Sargassum proliferation in SW Atlantic

Update from the Guianas,

In French Guiana they had proliferation of Sargassum since mid March which
has severely impacted artisinal fisheries catches as well as nesting sea
turtle numbers. In Suriname Sargassum started piling on our beaches at the
end of March, but it started disappearing again in April (although I
understand from fishermen that they are still having some reduced catches
due to it getting stuck in their nets). Guyana is currently experiencing
Sargassum along their shores, again fishermen are indicting a substantial
reduction in catches. So it seems to have moved along our shores from east
to west (which is the direction of the Guiana current) from mid-March to
now. Last year we had no Sargassum.
