The aim of this study was to investigate the effects of replacing different proportions of fishmeal with Clanis bilineata larvae (CBL) on the growth performance, body composition and non-specific immune index of white shrimps (Penaeus vannamei). CBL was used to replace 0 (CBL0), 25% (CBL25), 50% (CBL50) and 100% (CBL100) of the fishmeal in the basic diet to formulate four kinds of test feeds with basically equivalent nitrogen and energy. CBL50 treatment increased body weight gain, feed efficiency, body protein, superoxide dismutase activity, catalase activity, acid phosphatase activity, lysozyme, disease resistance ability against Vibrio alginolyticus and decreased body lipid level of shrimps compared with those of the control group. However, a high level of CBL (CBL100) decreased its efficiency compared to moderate level of CBL (CBL50). The results indicated that CBL may be used as a feed source with appropriate level to improve growth performance and immunity of white shrimp. •Clanis bilineata larvae increased growth performance of shrimp.•Clanis bilineata larvae modulated body composition of shrimp.•Clanis bilineata larvae increased SOD, CAT ACP and LZM activities of shrimp.•Clanis bilineata larvae increased disease resistance ability of shrimp.
