Development and drift of northern shrimp larvae ( Pandalus borealis ) at West Greenland
This is the first study of the West Greenland offshore population of Pandalus borealis in recent history that covers all larval stages. Shrimp larvae were sampled on the fishing banks off the west coast of Greenland from 63.5°N to 67°N in May, June and July. Abundances decreased during the summer as...
