The survey in Div. 3NO of NAFO Regulatory Area was initiated by Spain in 1995. Until 2001, the survey was carried out in spring (May), on board the Spanish vessel C/V Playa de Menduiña (338 GT and 800 HP) using bottom trawl net type Pedreira. Since 2001, the R/V Vizconde de Eza replaced the C/V Playa de Menduíña as the research vessel for the survey, and Campelen net replaced Pedreira net as survey gear. The main objectives of this survey time series are: a) to obtain biomass and abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.
The surveys on NAFO Regulatory Area of Div. 3L (Flemish Pass) were initiated by Spain in 2003. The surveys were carried out by the R/V ¿Vizconde de Eza¿ following the same procedures and using the same bottom trawl net type Campelen.The main objectives of this survey time series are: a) to obtain abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.
