AbstractSince 2003, a stratified random summer bottom trawl survey in the NAFO Regulatory Area of Division 3L (Flemish Pass) was conducted by Spain. 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 2003-2008. For Greenland halibut an increasing trend along the whole period in biomass and abundance is observed. A good recruitment, mainly in 2006, can be seeing; although the number of individuals of length over 70 cm. is very low. The American plaice biomass has increased since 2004 and a presence of small individuals in the last years is observer. For witch flounder,there is no a clear trend in the period 2003-2008, in 2008 the biomass increased.
