Abstract:To investigate the effects of high level of lupin meal (LM) supplemented with organic selenium (OS) on the growth and blood biochemistry of barramundi (Lates calcarifer), four isocaloric and isonitrogenous diets were prepared, containing either non‐fermented or fermented LM, and either supplemented with 2 mg OS/kg (LM, LMOS, FLM and FLMOS), or not. A fishmeal (FM)‐based diet formulated for juvenile barramundi was used as a control diet. Fish (initial mean weight of 5.88 g) were triplicated and fed the test diets for 75 days. The findings demonstrated that growth performance of fish fed with the FLM and FLMOS diets were similar to fish fed with the FM diet (> .05). The antioxidant glutathione peroxidase (GPx) activity, and haemoglobin (Hb) of fish fed with the FLMOS diet were significantly higher than that of FM‐fed fish (< .05). Plasma alanine aminotransferase (ALT) activity was significantly increased in fish fed with non‐fermented diets (LM and LMOS) than in those fed with fermented LM diets (FLM and FLMOS) (< .05). However, there were no significant differences in ALT activity among LMOS, FLM, FLMOS and FM diets. There was an interaction between the LM and OS on plasma CK activity; the CK of fish fed with diets supplemented with OS was higher in non‐fermented LM diets but lower in fermented LM diets (< .05). This study suggests that fermented LM have an obvious potential to substantially replace 75% FM protein in the diets of barramundi.
