Since 1995, a stratified random spring bottom trawl survey in the NAFO Regulatory Area of Div. 3NO was conducted by Spain. In 2001, the trawl vessel was replaced; so, the time series indices were transformed. The transformed entire series of mean catches, biomass and length distribution for redfish (Sebastes marinus, Sebastes mentella and Sebastes fasciatus collectively reported) are presented for the period 1995-2000, and the no-transformed data for the years 2002-2009. In 2001 there are data from the two vessels. The summed biomass based on conversion of the length frequencies are presented and compared to the estimates from the method used to convert the CPUE. The indices of this species were variable over the time, with a sharp increase in year 2009. There are no recent good recent recruitments.
