Seaweed Farms, Zanzibar (IMAGE) Terry Collins Assoc Caption Increasingly, seaweed cultivation is being integrated with intensive fish farming to provide nursery grounds for juvenile commercial fish and crustaceans, and to filter undesired nutrients and improve the marine environment and reduce eutrophication.
