The enzyme activities of juvenile channel catfish fed different types of soybean diets. Head kidney, liver and spleen were collected from six groups of channel catfish at the end of the eight-week experiment, and (A) LDH, (B) T-AOC, (C) AST, (D) ALT were measured. The abscissa represents the sample type (Head kidney, Liver and Spleen) and different colors represent different sample groups. Data are presented as mean ± SE (n = 3). *p < 0.05 versus JACK (t-test).
