| Five isonitrogenous and isoenergetic experimental diets of juvenile Pelteobagrus fulvidraco were formulated by replacing 0%, 15%, 30%, 45%, and 60% of fishmeal with cricket meal, named T0, T15, T30, T45, and T60, respectively. The experimental fish were cultured for 10 weeks. The results showed that with an increase in cricket meal content, the final body weight, weight gain rate, and specific growth rate of juvenile P. fulvidraco increased first and then decreased. The FBW, WGR, and SGR in T30 were significantly higher than those of T0, whereas the feed conversion ratio was significantly lower than those of T0 and T15. The hepatosomatic index in T30 was significantly higher than those of T0 and T15. The essential amino acid contents in juvenile P. fulvidraco muscle, arginine, and valine in T60 were significantly higher than those of T0. Compared with the T0, the content of glucose in the serum of T30, T45, and T60 had significantly increased, whereas the content of total cholesterol was significantly decreased. The activities of the serum superoxide dismutase and catalase in T30 and T60 were significantly higher than that of T0. In conclusion, these results suggested that replacing fishmeal with cricket meal has no effect on growth performance and muscle amino acid contents, and improves serum antioxidant capacity in juvenile P. fulvidraco. |
