Modelling the advection and diffusion of eggs and larvae of Greenland halibut ( Reinhardtius hippoglossoides) in the north‐east Arctic
Abstract Since the late 1980s there has been considerable uncertainty in recruitment levels of the north‐east Arctic stock of Greenland halibut ( Reinhardtius hippoglossoides ). The abundance of several year classes, originally considered very low at 0–3 yr age, appeared higher than expected at the...
