Bold values indicate models with the lowest AICc, a ∆AICc < 1, and the greatest wi(AICc). Explanatory variables include TL, total length at stocking; SB, body shape; SH, head shape; BP, number of visits at the distant feeding spot within ponds; SP, time spent sheltering within ponds; G, growth rate in ponds over 58 days.
