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 1800. Entire series of mean catches, biomass and length distribution for Greenland halibut, American plaice and witch flounder are presented for the period 2003-2015. Greenland halibut biomass and abundance estimates show an increasing trend since 2011, reaching the maximum values in the series in 2008 and 2014. In last years it can be seen a presence of juveniles (around 12-15 cm). American plaice biomass and abundance estimates present an increasing trend since 2010, reaching in 2015 the highest value in the series. Regarding witch flounder, the biomass and abundance increased in 2015, but there is no a clear trend in the whole period 2003-2015. Postprint 0,0000
