By-catch in the Spanish Greenland Halibut Fishery (NAFO Divisions 3LMNO): 1991–94
The species composition of by-catch was studied in the Spanish Greenland halibut (Reinhardtius hippoglossoides) fishery, developed in the NAFO Regulatory Area in Div. 3L, 3M and 3NO, for the period 1991–94. Of the 17 species occurring in the catches, two groups were identified as the more and less f...
