Sargassum off the Scarbrough harbour yesterday.

Sargassum in Tobago continues to affect fishermen.

On Sunday, fisherman Arthur Stewart who operates out of Scarborough told Guardian Media that the problem was not only a coastal one.

Stewart, who said he has been fishing when he was in primary school in the 1950s, said fishermen who set fish pots are affected by the seaweed since the sargassum can drag away the fishing buoys or cause it to sink. He said fishermen who troll for fish also run into heavy problems when the seaweed tangles with their lines.

Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side.

He explained that the seaweed can also cause problems for fishermen who do not use a jetty and are anchored on the beach since they find it extremely difficult to dock and anchor boats.

Heavy volumes of the sargassum seaweed have been engulfing coastlines in the Trinidad and Tobago and the Caribbean since 2015.

While it does bring with it an odour, researchers have been trying to find ways to capitalise on any possible commercial use.
