Results for Greenland Halibut and American Plaice of the Spanish Survey in NAFO Divisions 3NO: Biomass, Length Distribution and Age Distribution for the Period 1997-2005
Greenland halibut (Reinhardtius hippoglossoides) and American plaice (Hipoglossoides platessoides) indices from the bottom trawl survey that Spain carries out in spring since 1995 in Divisions 3NO of the NAFO Regulatory Area are presented. Biomass, length distribution and age distribution are presen...
