Northeast Arctic Cod and Prey Match-Mismatch in a High-Latitude Spring-Bloom System
By combining an ocean model, a nutrient-phytoplankton-zooplankton-detritus-model and an individual-based model for early life stages of Northeast Arctic cod we systematically investigate food limitations and growth performance for individual cod larvae drifting along the Norwegian coast from spawnin...
