文摘

Atlantic cod of initial mean weight ~220 g were fed a control diet and three diets in which fish meal(FM) was replaced with increasing levels of full-fat soybean meal (FFS) supplied at 12, 24, and 36%of dry diet, for 12 weeks. There were no significant differences in final weights, but the specific growthrate (SGR) was significantly higher in fish fed the control (FFS0) diet compared to fish fed the FFS12and FFS36 diets, and the feed conversion ratio (FCR) was significantly lower in fish fed the FFS0diet compared to the other three treatments. The fatty acid (FA) compositions of the cod muscle andliver were highly affected by dietary treatment, and linear relationships between dietary and tissueFA concentrations were shown for some of these. Moreover, selective utilization or accumulation inthe tissues of specific FA was suggested by the results.
