Atlantic cod of initial mean weight approximately 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 growth rate (SGR) was significantly higher in fish fed the control (FFS0) diet compared to fish fed the FFS12 and FFS36 diets, and the feed conversion ratio (FCR) was significantly lower in fish fed the FFS0 diet compared to the other three treatments. The fatty acid (FA) compositions of the cod muscle and liver were highly affected by dietary treatment, and linear relationships between dietary and tissue FA concentrations were shown for some of these. Moreover, selective utilization or accumulation in the tissues of specific FA was suggested by the results.
初始平均体重约220克的大西洋鳕鱼被投喂对照饲料以及三种饲料，其中鱼粉（FM）被不同水平的全脂豆粕（FFS）替代，替代水平分别为干饲料的12%、24%和36%，持续投喂12周。最终体重没有显著差异，但与投喂FFS12和FFS36饲料的鱼相比，投喂对照（FFS0）饲料的鱼的特定生长率（SGR）显著更高，并且与其他三种处理相比，投喂FFS0饲料的鱼的饲料转化率（FCR）显著更低。鳕鱼肌肉和肝脏的脂肪酸（FA）组成受饲料处理的影响很大，并且其中一些显示出饲料和组织FA浓度之间的线性关系。此外，结果表明特定FA在组织中的选择性利用或积累。
