a There is no effect of early-life activity on the maximum predicted size Linf, but early-life feeding behavior and reproductive output are indirectly connected via growth: (b) individuals that feed more grow to a larger size (feeding is presented as mean ± SD, N = 932 feeding measurements), and (c) larger fish produce larger offspring. f Larger fish also start reproducing later but (e) individual maximum size and brood size are not linked. a–e Shown are individual means (points) ± SD (error bars) (N (activity measurements) = 941, N (feeding measurements) = 932, N (size measured offspring) = 2522, N (broods) = 152). b, c, f Regression lines (black) and 95% confidence intervals (gray shadow) were estimated via linear mixed-effects models. d Shown are individual von Bertalanffy growth curves (lines) and raw data (points). a–f Coloration by average time spent feeding (yellow represents long feeding times, black represents short feeding times).
