Chinese longsnout catfish (Leiocassis longirostris Günther) is a promising species freshwater catfish widely cultured in China. In this study, two growth trials were conducted to investigate the effect of different feeding strategies (TA: apparent satiation, TB: optimal feeding rate from bioenergentic modeling, TC: 80% optimal feeding, TD: 50% optimal feeding and TE: 2 weeks satiation and one week feed deprivation cycling) and feed composition (Cont: control, HP: high protein, HC: high carbohydrate, HL: high lipid, HE: high energy) on growth, feed utilization and meat quality of experiment fish 48g and 80g for 100d and 90d respectively. Feed deprivation and freezing also conducted to invest its effect on the quality of the fish. The result suggested that decreased feeding ration properly can save feed; improve fish skin colour, improved flesh texture, increased economic and reduced water pollution. Among feed composition, group of HC can inhibit fish growth. Lipid content in feed can influence experiment fish quality significantly and texture became soft after freezing. The present study also found that flesh hardness, gumminess and chewiness decreased with the freezing time in the same trend and can describe the flesh texture change compared with cohesiveness, springiness and resilience. Optimal feeding rate group and high protein group had highest collagen content。The experiment had found the main effect which influence fish quality, main evaluation factor and its meaning to the fish quality when changed.
