The interactive effects of temperature and food consumption on growth of larval Arctic cod (Boreogadus saida)

Understanding larval growth, mediated by the interaction of early life traits and environmental conditions, is crucial to elucidate population dynamics. We used a bioenergetic model as an integrative tool simulate growth Arctic cod (Boreogadus saida) larvae test sensitivity modeled temperature food quantity quality. The was computed energy gained through consumption minus lost respiration other metabolic processes. extended previously published cover full range length simplified feeding module. This simplification allowed us build predictive that can be applied at large spatial scale. Our suggested with subzero temperatures in High Arctic, need increase order reach observed length-at-age late summer. agreed well field observations but 2–3 times higher than laboratory-derived rate, probably due differences type selective mortality. study reveals important knowledge gaps our understanding including lack empirical estimations daily ration for under natural habitat temperatures.
