Abstract: Objective The search for insect protein sources as alternatives to fish meal is a current hot topic in aquaculture nutrition research. This study aims to investigate the effects of dietary cricket meal supplementation on the growth performance, body composition, digestive enzyme activities, and liver antioxidant capacity in juvenile Leuciscus waleckii. Methods A total of 450 juvenile L. waleckii with an average weight of approximately (16.27±0.05) g were subjected to 56 days feeding trial. Experimental diets included cricket (Gryllulus) meal replacing fish meal at levels of 0% (P0 control group), 5% (P5 group), 10% (P10 group), 15% (P15 group), and 20% (P20 group). Results 1) At the end of the feeding experiment, compared with the control P0 group, no significant differences were observed in final body weight (FBW), weight gain rate (WGR), specific growth rate (SGR) and feed conversion ratio (FCR) among all the experimental groups; however, the viscerosomatic index (VSI) in the P20 group significantly decreased (P<0.05). 2) There were no significant differences in the whole-body composition (moisture, crude protein, crude lipid, and crude ash) among all the groups. 3) Compared with the control P0 group, the activities of lipase and pepsin in all experimental groups were significantly increased (P<0.05); the activity of α-amylase in the P20 group was significantly higher than that in the control P0 group and the other experimental groups (P<0.05). 4）The malondialdehyde (MDA) content in the liver of the P15 group was significantly lower than that in the P20 group (P<0.05); the catalase (CAT) activity in the liver of the P10, P15, and P20 groups was significantly higher than that in the control group P0 (P<0.05). Conclusion Under the conditions of this study, the replacement of fishmeal with an appropriate proportion of cricket meal did not negatively affect growth performance of juvenile L. waleckii but enhanced intestinal digestive enzyme activities and liver antioxidant capacity, with the 15% replacement level showing optimal effects. These findings provide data support for the development and application of fish meal-based diets and low-fish meal formulated feeds for juvenile L. waleckii.
