Results for the Roughead Grenadier from the Spanish Surveys Conducted in the NAFO Regulatory Area of Divisions 3NO, 1997-2004
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 were transformed. The transformed entire series of mean catches, biomass and length distribution for Roughead...
