THE POTENTIALITY OF MICROALGAE AS A SOURCE OF DHA AND EPA FOR AQUACULTURE FEED

Microalgae have the various function with positive health effects. For not only human beings, but also its potentiality has important roles for aquaculture system. Microalgae provide the essential fatty acids namely PUFAs. The long-chain polyunsaturated fatty acids (PUFAs) with two most important parts; Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA) …
