The Boreoatlantic gonate squidGonatus fabricii: distribution and size off West Greenland in summer 1989 and in summer and autumn 1990

Abstract The Boreoatlantic gonate squid Gonatus fabricii is the most abundant squid in the offshore arctic and subarctic waters of the northern Atlantic. Adults are common in midwater while juveniles occur in surface waters close to the continents. As part of a research project focussing on the inte...
