Since 2003, a stratified random summer bottom trawl survey was conducted by Spain in the NAFO Regulatory Area of Division 3L (Flemish Pass). The surveys were carried out by the R/V “Vizconde de Eza” using bottom trawl net type Campelen. Entire series of mean catches, biomass and length distribution for Greenland halibut, American plaice and witch flounder are presented for the period 2003-2010. Greenland halibut biomass and abundance estimates present a slight increase this year being the second highest value of the series. A poor recruitment and low number of individuals of length over 70 cm can be seeing in 2010. American plaice biomass has decreased in 2010 reaching one of the lowest value in the series. A presence of small individuals is also observed in 2010 as in the previous years. For witch flounder, the biomass and abundance increased in 2010, showing a slight increasing trend since 2007.
