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 2003-2011. Greenland halibut biomass and abundance estimates show a decrease in the latest year; which represent one of the lowest values of the series. American plaice biomass has a slight increase this year. Regarding witch flounder, the biomass and abundance decreased in 2011, but there is no a clear trend in the period 2003-2011.
