Standardized CPUE Indices for Greenland Halibut and American Plaice in NAFO Divisions 3LMNO Based on Spanish Commercial Catch Rates
Standardized cpue series using a Generalized Linear Model for Greenland halibut and American plaice in Division 3LMNO, based on catch and effort data from the Spanish trawl fleet since 1990 at depth intervals are presented. In the case of the Greenland halibut series, the largest proportion of the v...
