The work aims to analyze the effects of seasonal change and growth cycle on the body color and nutritional composition difference of cultured Pseudosciaena crocea, by comparing the difference in the body shape and nutritional composition of cultured Pseudosciaena crocea, with the Pseudosciaena crocea in purse seine culture as the study object. With the wild Pseudosciaena crocea (W) as the control group, the Pseudosciaena croceas in different culturing stages (S0 for July, S1 for October, S2 for January of next year) were analyzed for body shape index, freshness index, color difference and nutritional index. The difference in body color and nutritional composition of Pseudosciaena crocea in different culture stages was comprehensively evaluated. The results showed that, the freshness of cultured and wild Pseudosciaena croceas reached the first level standards; the body length/height of wild fish was larger than that of cultured fish; the fatness of wild fish was larger than that of cultured fish; and the fat content was in decline. The b* value of wild fish>S0 (P<0.05), but＜S1 and S2 (P>0.05). ΣSFA of wild fish was significantly larger than that of cultured fish (P<0.05). ΣMUFA of wild fish was larger than that of cultured fish. ΣPUFA and Σ (EPA+DHA) of wild fish were lower than those of cultured fish. IA and IT of wild fish were larger than those of cultured fish, but PI value was lower than that of cultured fish. The wild and cultured fish both expressed the rule NEAA>EAA>SEAA. The TAA content of wild fish was higher than that of cultured fish. F value of wild fish was smaller than that of cultured fish. The first restrictive amino acids of wild fish and S2 were valine, and the second restrictive amino acid was methionine + cystine. However, S0 and S1 were on the contrary. The culture cycle of purse seine culture of Pseudosciaena crocea can greatly affect the body fatness and fat content.
