Biochemical composition and nutritional value in the muscle of yellowback seabream Dentex tumifrons(Temminck & Schlegel,1843),wild-caught in the East China Sea,China
Biochemical composition and nutritional value in the muscle of wild-caught Dentex tumifrons in the East China Sea were determined,evaluated and compared with another three maricultured sparids,Acanthopagrus schlegilii schlegilii,Pagrus major and Rhabdosargus sarba.The muscle of D.tumifrons consisted of 18.30% crude protein and 0.47% crude lipid;crude protein was higher and crude lipid lower than A.schlegilii schlegilii,P.major and R.sarba.In the muscle of D.tumifrons,the total essential amino acids(EAA)required by humans comprised 42.88% of total amino acids,higher than A.schlegilii schlegilii,P.major and R.sarba.The first limiting amino acid (s)was Threonine(Thr)based on the amino acid score(AAS),and were Methionine(Met)and Cysteine(Cys)based on the chemical score(CS).The EAA index was 65.79.Totally 19 fatty acids were determined.Eicosapentaenoic acid(EPA)and docosahexaenoic acid(DHA)contributed to 22.65% of the total fatty acids with 17.25% from DHA.Biochemical composition and nutritional value in the muscle of wild-caught Dentex tumifrons provide information on food quality and nutritive requirement and composition of the species,which will help to develop resembling feeds for its mariculture.
