Results of the factorial design ANOVA and Tukey HSD post hoc test (at P < 0.05) on the effect of stocking season, lake area (S = Siófok, Sz = Szemes and K = Keszthely basin), method (shore vs. offshore release) and fish size groups (M1 to M5 represent increasing fish mass) on arcsin square root transformed 1460 days recapture rate by anglers (%), and log10(x + 1) transformed days spent in lake and distance travelled between release and recapture sites of tagged pikeperch in Lake Balaton. Since size of stocked fish varied between seasons, thus when full model indicated seasonal variability, main effect of season was also tested for each size group separately.
