“…The liver condition of north‐east Arctic G. morhua has been linked to M. villosus biomass (Yaragina & Marshall, ) and other studies have indicated that M. villosus biomass could be important for growth of G. morhua (Dalpadado & Bogstad, ). Additionally, density dependence has been shown to affect the growth of G. morhua with higher abundance leading to depressed growth (Sinclair & Swain, ; Anderson, Ottersen & Swain, ). We found a correlation among L ∞ and either G. morhua landings (in M10) or R cod or (in M11).…”

This study assesses spatiotemporal and sex‐specific growth of Atlantic cod Gadus morhua in Icelandic waters. We use a Bayesian approach which lends itself to fitting and comparing nested models such as these. We then compare fitted parameters of these models to potential explanatory variables using a redundancy analysis (RDA) to look for drivers of growth in G. morhua. Results indicate that models that incorporate differences in growth among time, space and sex are the best‐fitting models according to deviance information criterion (DIC). Results from RDA indicate that capelin Mallotus villosus recruitment and biomass is highly correlated with deviations in the von Bertalannfy growth parameter k and that L∞ is correlated with G. morhua landings in the model that uses year to account for time‐varying growth and estimated G. morhua recruitment in the model that uses cohort to account for time‐varying growth.
