A 75-day feeding trial was conducted to investigate the influence of different phosphorus levels on grass carp (Ctenoparyngodon idellus) physique and the bone deformity identification of grass carp. A total of 270 grass carp with an average body weight of 22.29 g were randomly divided into 6 groups with 3 replicates and 15 fish per replicate. The fish in the 6 groups were fed 6 purified diets containing graded levels of calcium biphosphate (0, 13, 29, 45, 61 and 77 g/kg, respectively). The results showed as follows: the specific growth rate of length in the group with the diet containing 29 g/kg calcium biphosphate was significantly higher than that in the groups with the diet containing 0 and 13 g/kg calcium biphosphate (P<0.05). The condition factor and snout-gill cover length/body length of grass carp were no significant differences by dietary phosphate level (P>0.05), while the bone deformity of grass carp was found in high phosphate level groups. According to the results, it is concluded that more than 29 g/kg of calcium biphosphate supplementation in the diet can affect the growth of grass carp, and lead to bone deformity. Based on the new angle between the main axis and vertebra, the grass carp physique is divided into 4 grades: healthy fish, mild deformity, moderate deform and severe deformity.
