The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are expected. This is especially true for species with long reproduction migration...
