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).
|PF||PF + NF|
|Mortality (%)||2.69 ± 0.76a||2.73 ± 0.63a|
|SL (mm)||43.14 ± 6.66a||44.42 ± 4.04a|
|W (g)||1.32 ± 0.41a||1.46 ± 0.45a|
|TWI (g)||371 ± 31a||470 ± 116a|
|SGR (% day−1)||3.85 ± 0.24a||4.60 ± 0.74a|
