This experiment was conducted to evaluate different artificially formulated feeds on promoting gonadal development in broodstock during the nutrient enrichment stage. Three kinds of formulated feeds, numbered diets no.1 (without krill meal), no.2 (10% krill meal), and no.3 (20% krill meal) were used as the experimental groups, with two replicates, and natural polychaete worm bait was used as the control group. The purpose of the experiment was to determine the appropriate formulated feed to enhance gonadal development in broodstock. The four treatment groups were fed the four different feeds for 60 d, and whole-body, hepatopancreatic, and gonad weights were determined. In addition, the fatty acid profiles of the four feeds and those of the hepatopancreas and gonads were analyzed in the four treatment groups. Fatty acid profiles of feed are important for gonadal development and reproduction in brood stock, as they can affect the hepatopancreatic and gonadal fatty acid profiles, as well as gonadal development. Eicosapentaenoic acid (EPA) docosahexaenoic acid (DHA), and arachidonic acid (AA) are three kinds of polyunsaturated fatty acids (PUFAs) that play significant roles in gonadal development. T he results showed that female broodstock in the control group had the significantly highest weight gain rate, which was (78.10±6.38)% (<0.05), compared with that of the others. No difference in weight gain rate (>0.05) was observed between female broodstock in the three formulated feed groups. Weight gain rate of male broodstock was lower than that of females. Males in the control group had the highest weight gain rate, but no difference (>0.05) was observed between males fed diets no. 3 and no. 2. Fish fed diet no.2 had the lowest hepatopancreatic index at (2.37±0.02)%; the hepatopancreatic index was not different (>0.05) from that in the control group, but was significantly different (<0.05) from that in the other two treatment groups. Fish fed diet no. 2 had a significantly higher (<0.05) gonadosomatic index (GSI) than that in the other groups, but no difference (>0.05) in GSI was observed between fish fed diet no.3 and the control group. The fatty acid profiles differed among the four feeds. More ∑PUFA was detected in than those in the artificially formulated feeds, and EPA, DHA, and AA contents in were higher than those in the formulated feeds. Diet nos. 2 and 3 had significantly more (>0.05) ∑PUFA as well as more EPA, DHA, and AA than those in diet no.1, indicating that the fatty acid profiles in diet nos. 2 and 3 were closer to those in . These results show that the fatty acid profiles in gonads were correlated with the fatty acid profiles in the brood stock feeds.
