Marine crustaceans are
important source of food in many countries and are known for their economic value. The present study was carried out to assess the biochemical composition of Litopenaeus vannamei
cultured under different percentage of alginate supplemental diet. The results showed that protein, carbohydrate and lipid varied significantly between different alginate supplemented diet groups of L. vannamei
day (P < 0.05). Essential amino acids were represented by arginine, cysteine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, tyrosine and valine and non- essential amino acids were alanine, asparagine, aspartic acid, glycine, proline, glutamine and serine. Compared to
control, fatty acids (SFA, MUFA and PUFA) and minerals (Ca, Mg, Zn, Fe and P) showed higher content in the tissues of L. vannamei
fed with diet supplemented with alginate. Our study showed that the shrimps fed with diet supplemented with alginate had a positive effect on biochemical composition.
