Data on sharks in NAFO Divisions 3LMNO: 1991-1998
A review of the species composition, distribution and abundance of sharks in both the Spanish commercial catches (1991-98) and research surveys (1988-98) are carried out. Shark species are by-catches of Greenland halibut fishery. The proportion of shark species in the total catch is small and the ma...
