Results for Greenland halibut and American plaice of the Spanish survey in NAFO Div. 3NO for the period 1997-2007
Greenland halibut (Reinhardtius hippoglossoides) and American plaice (Hippoglossoides platessoides) indices from the bottom trawl survey that Spain carries out in Spring since 1995 in div. 3NO of the NAFO Regulatory Area are presented. Mean catch per town, biomass and length distribution for both sp...
