Figure 1. Sizes of trout sampled from the wild. (A) Size distribution of all trout (N = 518) with the bimodal normal distribution (green line; AIC = 4278.3) that fit the data better than a normal distribution (AIC = 4465.1). (B) Sizes of trout that were genetically sexed and assigned to one of the experimental families or to the non-experimental ones (blue = male, red = female). The hatched line indicates the largest size of 0+ fish based on a Bayesian mixture model (Supplementary Material) and that is supported by the genetic assignments of known 0+. (C) Sex ratio (% males) among captive-bred and wild-born that were identified as 0+. The dotted line indicates the 50% male ratio. See text for statistics.
