摘要：

In this study, 640 golden pompano (mean initial weight of 82.85 +/- 2.36 g) were randomly allocated into 32 floating net cages. Eight experimental diets involving various lipid sources were given. They were: fish oil (FO), krill oil (KO), soybean oil (SO), corn oil (CO), 1:1 FO-SO, 1:1 FO-CO, 1:1 KO-SO and 1:1 KO-CO. The results showed that the specific growth rate in the SO, CO, 1:1 FO-SO and 1:1 KO-SO groups was significantly lower than in the FO group (P<0.05), and the 1:1 KO-CO had lower feed conversion ratio (FCR) among all the diets. The muscle fatty acid compositions were closely correlated with the fatty acid composition of the diets. Moreover, the serum MDA content of golden pompano fed the other seven diets was significantly lower than that of the fish fed the FO diet (P<0.05) except for the 1:1KO-CO diet, with the lowest MDA content, which occurred in KO diet. Accordingly, we concluded that the FO, KO, 1:1 FO-SO and 1:1 KO-CO diets resulted in improvements in growth performance in golden pompano. Moreover, KO diet regulated some physiological and biochemical indicators. This study could provide a basis for the response-based selection of optimal lipid sources.
