Description
Summary: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. Following the recommendations of the 2000 Scientific Council Meeting, the entire series of abundance and biomass for American plaice are presented for the period 1995-2001. The indices calculated from the survey series shows a general increasing in the American plaice abundance and biomass in this period, and an important recruitment in the area in last years; this data suggest a recuperation of the stock.
