Results for the Greenland Halibut in the Spanish Spring Survey in the NAFO Regulatory Area of Divisions 3NO, 1996-2001: Abundance, Biomass and Population Structure
Since 1995, a stratified random spring bottom trawl survey in the NAFO Regulatory Area of Div. 3NO was conducted by Spain. The depth strata surveyed was extended to 1464 m. The main propose of the surveys was obtain abundance and biomass indices for the commercial species in the area. The entire ser...
