Small amounts of Sargassum washing ashore is a normal and natural phenomenon in the Caribbean, this helps protect beaches from erosion and brings essential nutrients to ecosystems

Sargassum provides a diverse habitat for marine invertebrates, arthropods, sea turtles, marine mammals, fish, seabirds, and more!

As rafts of sargassum move closer to shore, animals that can leave

abandon the patch for more favorable habitats.

~

Small animals like shrimps and snails are not able to leave.

In nearshore areas, Sargassum becomes a problem for fishermen,

recreational boaters, businesses, and beachgoers . . .

Issues with Inundation

Inundations of Sargassum have caused environmental, human health, and economic concerns:

Decaying Sargassum releases toxic hydrogen sulfide gas, which can

negatively affect human health and marine life

~

Clogs fishing nets, impedes boating, and reduces areas for tourism and recreation

~

Decreases light penetration and oxygen levels, harming coral reefs and seagrass beds

~

Removal efforts can increase beach erosion
