A review on roughhead grenadier (Macrourus berglax) biology and population structure on Flemish Cap (NAFO Division 3M) 1991-2006 based upon EU Flemish Cap bottom survey data
The European Union has conducted since 1988 an annual bottom trawl survey in Flemish Cap (NAFO Div. 3M) in the 200-720 m depth range. The information on roughhead grenadier population structure recorded during the last 16 EU surveys (1991-2005) in Flemish Cap is presented. Depth distribution of captures, length/age distribution of captures, growth rates, sex-ratios, catch curves, and abundance/biomass estimated by the swept area method are presented. In general, the biomass index increased from low levels to a peak of about 3000 tons in 1993, then decreased in 1994 and remained around 1500 and... Mehr ...
