The studies on fatty acids of some strains of microalgae have been implemented (Ronquillo et al., 2012, Liang et al., 2004, Hoa et al., 2010). Still, not much studies on the nutrient content included fatty acid composition of microalgae have been carried out in mangrove area of Vietnam. Thus, present study aims to identify nutrient content of microalgae from mangroves of Xuan Thuy NP in order to contribute in improving quality of alga-based food source cultivated for coastal aquaculture. | Identification of nutrient composition of some isolated microalgae from mangroves of Xuan Thuy national park
