Age- and length-based model fits with AIC values and AIC weights.

Note that the age-based models were estimated on a reduced dataset and are not directly comparable to length-based models. The base model is identified with *, the spatial model (unweighted and weighted) is identified with †. Models are ranked from best to worst fitting. Where age = is the numeric fish age, length = individual fish length, lon = longitude in decimal degrees, lat = latitude in decimal degrees, year = the year sampling occurred as a factor, haul = individual hauls that samples originated from, incorporated as random effects, (e)df = model estimated degrees of freedom, AIC = Akaike information criterion, Δi = AIC difference, AIC weights is the relative likelihood of a model, f = smooth terms. Age and length models were fit on different datasets as more length data are available.
