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...

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 for American plaice are presented for the period 1995-2000, and the no-transformed data for the years 2001-2003. The standard deviation are shown for abundance and biomass. The summed abundance and biomass based on conversion of the lenght frequencies are presented and compared to the estimates from the method used to convert the CPUE. The results from the lenght distribution are smaller in all cases. A decreasing in American plaice abundance and biomass is observed in last years (2001-2002), although this recent year an increasing occurs.
