The common squid (Loligo vulgaris) and other cephalopod species are of economic significance, especially in southern Europe. Landings from the fishing sector are decreasing, however. For one thing, because the size of the squid populations is strongly influenced by environmental factors, and for another probably because squid are too intensively fished. There is no effective fisheries management, although this would be urgently needed.
The ice-cold northern seas are not only the home of king crab (Paralithodes camtschaticus), but also of queen crab, also known as snow crab (Chionoecetes opilio). The snow white meat of the long spiderlike legs has an intense, slightly salty yet delicate flavour. The queen crab fishery is sustainable, and annual landings add up to well over 110,000 tonnes.
