Four practical diets containing different levels of soybean cake (0, 155, 320, 490 g kg −1 ) were prepared to investigate the effect of replacement of fishmeal by soybean cake on the Chinese longsnout catfish ( Leiocassis longirostris Günther) during a 62‐day growth trial. The diets were isonitrogenous, isoenergetic and contained about 430 g kg −1 crude protein and 20 MJ kg −1 gross energy. With increasing levels of dietary soybean cake, growth rate and feed utilization decreased; feeding rate and the contents of dry matter, fat and energy of fish body were not significantly affected while body protein showed lowest value in the fish fed the diet containing 320 g kg −1 soybean cake.
