Main research findings
The recruitment to the cod stock in the Barents Sea varies greatly from year to year, with consequences for the ecosystem and fisheries. The mechanisms behind and the reasons for this variation are still unclear. We shed light on factors that affect the survival and geographical distribution of the earliest life stages, that is, eggs and larvae. The statistical analyses indicate that the age distribution of the spawning stock affects the larval abundance, and that the condition of the spawners affects the larval distribution. Numerical modeling results suggest that the positive effects of high temperature on growth, survival, and ultimately recruitment are, on average, greater than the negative effects of food restriction. These findings reveal mechanisms that contribute to the varied distribution, growth and survival of cod from spawning and through the first years of life.
