Fig. 1. Apparent digestibility coefficients (ADC) of starch (mean ± s.d., n = 3) from differ- ent plant sources for jundiá catfish and Nile tilapia juveniles. a,b,c,dDifferent letters indicate different means by Tukey test (P b 0.05). Vertical bars indicate standard deviation. Block: P = 0.0855; Plant source: P = 0.0005; Fish species: P b 0.0001; Plant source × Fish species: P = 0.0027.
