Abbreviations: EF, electrofished; FF, pure farm group; h², narrow sense heritability; L_F, fork length; r_E, residual correlation between L_F and mass; r_P, raw phenotypic correlation between L_F and mass; r_G, additive genetic correlation between L_F and mass; V_P, raw phenotypic variance; V_A, additive genetic variance; WW, pure wild group.

For V_A, h², r_G and r_E, estimates are posterior modes, with credible intervals in parentheses. L_F and mass were natural log transformed in all models.
