Evaluation of nutritional composition in muscle of wild and farmed Siniperca chuatsi in Poyang Lake basin
This study aimed to investigate the nutritional components of the muscle in wild and farmed Siniperca chuatsi from the Poyang Lake basin.A total of 30 wild and 30 farmed Siniperca chuatsi from the Poyang Lake basin were selected and the contents of conventional components,amino acids,fatty acids,and minerals in muscle were detected.The results showed that the moisture content in the muscle of the wild samples was significantly higher than that of the farmed samples(P＜0.05),while the crude protein and crude fat content were significantly lower than those of the farmed samples(P＜0.05).The types of amino acids in the muscle of wild and farmed Siniperca chuatsi were identical,with the histidine content in the muscle of the wild samples(0.34％)being significantly lower than that of the farmed samples(0.36％)(P＜0.05).The amino acid composition of the muscle in both wild and farmed Siniperca chuatsi from the Poyang Lake basin met the FAO/WHO standards.The EPA content in the muscle of the wild samples(1.33％)was significantly higher than that of the farmed samples(0.34％)(P＜0.05),and the DHA content(2.66％)was significantly higher than that of the farmed samples(1.10％)(P＜0.05).The selenium content in the muscle of the wild samples(0.45 mg/kg)was significantly higher than that of the farmed samples(0.23 mg/kg)(P＜0.05).The study indicates that the muscle amino acid composition of wild and farmed Siniperca chuatsi from the Poyang Lake basin is quite similar,both possessing high nutritional value,and that the nutritional indicators of Siniperca chuatsi in the Poyang Lake basin under farming conditions are essentially comparable to those of the wild samples.
