Table 1. Summary of model diagnostics and fit for four candidate population models.

Model diagnostics (−ln (L), number of parameters (K), Akaike Information Criteria (AIC), corrected AIC (AIC_c), and model weights) for the four candidate models. Seasonal indicates whether a seasonalized (Yes) or traditional (No) von Bertalanffy growth function was fit to the data. Variance at age indicates whether variance in size-at-age was held constant across ages (Fixed) or allowed to vary among ages (Variable).
