Model statistics for spawning stock–recruitment models for the full Jones Length Cohort Analysis (LCA) 1995–2020 time series (26 yr) and for shorter time series lengths (15 to 25 yr) of Micropogonias megalops in NGC. Value of k is the number of parameters for each model; AICc is corrected Akaike Information Criterion, Δm is Akaike differences and wm is Akaike weight for each model.
