Standard length (SL), weight (W), total weight increment attained (TWI) and specific growth rate (SGR) for vimba bream used as trainer fish at the end of the experiment in group A (pikeperch with trainer fish and direct application of pelleted feed − PF) and B (pikeperch with trainer fish and gradual addition of pelleted feed to natural food − PF + NF). Data are presented as mean ± standard deviation. Values in the same row with different superscripts differ significantly (α = 0.05).
