Blue whiting distribution and migration in Greenland waters
Here, we provide the first comprehensive documentation of the north-western extreme of the blue whiting (Micromesistius poutassou, Risso 1827) distribution in Greenland waters. We compile data from hydroacoustic surveys, commercial fisheries, and bottom trawl surveys (1981–2017) and use age specific...
