Temporal and spatial patterns in the distribution of squid Loligo spp. In United Kingdom waters
A Geographic Information System (GIS) was used to test hypotheses regarding the spatial distribution of the squid Loligo forbesi and Loligo vulgaris vulgaris in the northern North-East Atlantic during the years1989-1994. Loligo spp. were present throughout coastal waters of the United Kingdom, but d...
