Study on Muscle Composition and Nutrition Requirements of Juvenile Summer Flounder(Paralichthys dentatus)

In this paper,the protein,lipid,ash,amino acid,fatty acid and other biochemical compositions in the muscle of juvenile Summer flounder are determined.It is shown from the determination results that the summer flounder is a kind of fish with high protein,low fat and low specific energy value,and the total amino acid content in muscle belongs to the medium level,but the essential and delicious amino acid contents are at high level.The ratio of branched chain amino acid and aromatic amino acid in the muscle protein is 2.794.The palmitic acid(16∶0) content in the fatty acid is the highest,the oleic acid(18∶1 n) and DHA(22∶6 n-3) contents are the next,and the summer flounder muscle is rich in EPA(22∶5 n-3) and DHA(22∶6 n-3),so the summer flounder has enriched and balanced nutrients and is a recommendable excellent cultured species and edible fish.
