American Plaice Biomass and Abundance from the Surveys Conducted by Spain in the NAFO Regulatory Area of Divisions 3NO, 1995-2003
Since 1995, a stratified random spring bottom trawl survey in the NAFO Regulatory Area of Div. 3NO was conducted by Spain. In 2001, the trawl vessel was replaced; so, the time series indices was transformed. The transformed entire series of mean catches, abundance, biomass and lenght distribution fo...
