Only the best‐supported models are shown and variables included in the best models are shaded in grey. Selected models for harbor porpoises are given separately for two different years (1994 and 2005) and for herring are given for different age groups (age 1 and ages 2 and 3). The biologic and physical variables are: bottom temperature (BT), maximum chlorophyll_a (CHL), net primary production (NPP), potential energy anomaly (PEA), depth‐averaged current speed (SP), and depth‐averaged vertical velocity from surface (DVV). L refers to likelihood model (B‐Binomial; G‐Gamma; P‐Poisson; Z‐zero‐inflated Poisson; N‐negative binomial). H refers to the hurdle models, ZIP refers to the zero‐inflated Poisson models. BM refers to the Besag–York–Mollie models for spatial effect, whereas SM refers to the stochastic partial differential equation models.

The SPDE and BYM models produced nearly identical results; as the datasets were identical we present only the BYM model selection results.
