Intensive cultivation of "Palmaria palmata" and evaluation of its chemical composition
Seaweed based Integrated Multi-Trophic Aquaculture (IMTA) systems are being designed to mitigate the environmental problems caused by several forms of fed aquaculture. A seaweed cultivation system using 127 and 230 L tanks was used to cultivate Palmaria palmata (Rhodophyta). Palmaria palmata is a co...
