Identification and chemical studies of pelagic masses of Sargassum natans (Linnaeus) Gaillon and S. fluitans (Borgessen) Borgesen (brown algae), found offshore in Ondo State, Nigeria
The pelagic seaweed found offshore and negatively impacting fishing activity in Ondo State Nigeria, has been identified to be a mixture of Sargassum natans and Sargassum fluitans which presumably floated from the Sagasso Sea of North Atlantic. In a bid to harness the potential uses of the seaweed bi...
