Aerial shots of what appeared to be remnants of an oil spill in the Essequibo River has turned out to be huge beds of sargassum seaweed which is now a major nightmare for fishermen.
The influx of seaweed has put a serious dent in the fishing industry, as fishermen have been forced to cut short their trips at sea with just small catches.
It has invaded coastal waters since February and is expected to be present for another two months.
