AbstractA growth experiment was conducted to determine the optimum dietary protein-to-energy (P/E) ratio of juvenile Chinese mitten crab Eriocheir sinensis. Six practical diets were formulated with P/E ratios ranging from 15.94 to 21.25gproteinMJ-1 gross energy (gMJ-1). Results showed that specific growth rates related with molting were significantly affected by dietary P/E ratio (P<0.05). The specific growth rates both in body weight (SGRw) and carapace width (SGRcw) for the entire experimental period were not significantly affected by dietary P/E ratio (P>0.05). Molting frequency, survival rate and crab body composition were also significantly affected by dietary P/E ratio (P<0.05). Rate of precocity displayed negative trends with growth rate, and the trend with SGRcw was significant (P<0.01). The activities of alkaline phosphatase, trypsinase and steapsin were significantly affected by dietary P/E ratio (P<0.05). Molting frequency (P<0.001), SGRw1-2 (P<0.05) and SGRw0-2 (P<0.05) were positively and significantly related to alkaline phosphatase activity. We recommend 18.1319.20gMJ-1 as the optimum dietary P/E ratio for juvenile E. sinensis, based on growth performance, rate of precocity and digestive enzyme activities.; A growth experiment was conducted to determine the optimum dietary protein-to-energy (P/E) ratio of juvenile Chinese mitten crab Eriocheir sinensis.
