Since 1995, Spain carries out a stratified random spring bottom trawl survey in Divisions 3NO of the NAFO Regulatory Area. In 2001, the trawl vessel and gear were replaced; so, the time series indices were transformed. The transformed entire series of mean catches biomass and length distribution for American plaice (Hippoglossoides platessoides) are presented for the period 1997-2000 and for Yellowtail flounder (Limanda ferruginea) for the period 1995-2000, and the both species no-transformed data for the years 2002-2004. For 2001, there are data from the two vessels. For American plaice we can see an increasing trend along the whole period. For this species, a good recruitment can be seen in 2004. For Yellowtail flounder, this is no a clear trend since 1998; its indices are almost constant along this period.
