Nutrient Profile of Large Yellow Croakers(Pseudosciaena crocea Richardson)Grown Under Different Aquacultural Settings

Nutrient contents of the large yellow croakers,Pseudosciaena crocea Richardson,grown in seine net,pond or net cage fed with same feed were compared with those of the fish caught in the wild.The results showed that(a)the protein content of the wild croakers was higher than those of the aquacultured counterparts,(b)the fat and energy contents and E/P ratio were lower in the wild than the aquacultured croakers,(c)the total,essential and essential for children amino acids were significantly different among the groups grown under different settings,(d)no significant difference was found in the flavoring amino acids orΣBCAA/ΣAAA in the fish raised in the different aquaculural settings(P>0.05),(d)the essential amino acid content in the fish was greater than 80% of the total amino acids,(e)the E/T and E/N ratios of all samples fell within the FAO/WHO model,(f)significant differences were found among the groups on the contents of saturated,monounsaturated and polyunsaturated fatty acids,as well as DHA+EPA andΣUSFA/ΣSFA(P<0.05),and(g)theΣSFA/ΣMUFA/ΣPUFA andΣ(n-6)PUFA/Σ(n-3)PUFA indices of the fish from all groups followed those formulated by Chinese Nutrition Society.Other than the fatty acids,all of the evaluation criteria on the croakers grown in seine net were the best among the fish from the tested groups.
