Sargassum Seaweed Around Barbados: Sightings & Possible Solutions

It arrived like a silent visitor…drifting in one area – then another – and another. Sargassum seaweed. Along the south east and north coasts of the island, heaps of the seaweed (locally called ‘moss’ but not the same as seamoss) are more prominent and seen along the shoreline.When it started rolling up on the south and west coasts where tourism is most prominent, tractors and troupes armed with rakes were sent to the shores to scoop up as many heaps as possible and dump elsewhere.

After a few days, the colour of it darkens as it’s dried by the sun, and acid is released into the atmosphere. With that comes a stench and countless clusters of tiny flies hovering over stinky heaps of seaweed brought on the sand by incoming waves at high tide.

In 2015, sargassum seaweed was a hot topic in Barbados and around The Caribbean. I wondered if many were pausing to consider that there could be a purpose for it or at the very least, a lesson to be learned from its arrival, even if that lesson was to observe our own reaction and sudden collective concern for the state of the sea and how it affected people on land.

Sargassum seaweed (sometimes called “moss”) has returned and is seen along some part of the island, mostly on, but not limited to, the east coast. The birds find the sargassum seaweed intriguing, sometimes swooping and sitting down on the mass to scout around for fish and other salty appetizers. Unfortunately, turtles that swim in the waters daily and come to shore to lay their eggs seasonally aren’t able to maneuver well in it and a few years ago (on the south east) I saw 3 big dead turtles upside down in a huge patch of the weed on the south east coast.

Barbados has been heavily economically dependent on tourism for many years, with turquoise beaches as the main attraction pitch so the sargassum flood stirred up conversations across the board. It wasn’t the fishermen only anymore but now hoteliers, restaurant owners and gov were directly being affected. Communication barriers were broken down and tractors were sent to clear mounds from several beaches and dump the seaweed elsewhere.

Discussions on its origin and possible uses flooded the internet, radio talk show programs, community conversations and print/online media.


Innovative gardening enthusiasts and farmers started collecting, drying and utilizing the seaweed as a natural fertilizer to nourish the earth and combat an unwanted and resilient crop consumer – snails. An update on this coming up in this same post so please read it.

Apparently, sargassum seaweed can also be a bio fuel source. For years, the seaweed passed by once a year, but as of 2015 it started arriving in droves and two years after its exodus, the shrub-like swimmer returns in short stints though in 2021, it stayed for months longer than usual.

Here’s a video I filmed of its movement across the water


  • 1. As of June 2nd, 2020 (years after this post was published here), a Barbadian chemist duo of OASIS Laboratory, is the first to launch a sargassum-based skin-care business.
  • 2. The seaweed is back again; so far I’ve seen it on the south east and south coasts. The new feature photo for this blog post was taken at Long Beach, Christ Church in May 2022.
  • Around July 2022, a minister in an online paper advised gardeners not to use this seaweed since it “was tested’ and mercury and more were found in it, but no details about who did the research or the amount of this or that allegedly in it.

Popular surfing spot Freights Bay, Christ Church late August, 2022. Just beyond here, on the way to Miami Beach the water near shore is completely turquoise. The sargassum seaweed gathers in some bays while others aren’t as heavily affected. Heavy rain either washes it in or out. Sometimes it’s fine (as is thinned out) and the seawater looks like loose-leaf tea.

Here’s a blue-water beach picture for a better understanding of how the sea (from the south to west coasts) mostly looks.
