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.
Get abundance indices of groundfish demersales species. Get the size structure of commercially exploited stocks. Collection of biological material. Prospecting deep zones.Get physical-chemical parameters of water in the study area. Sampling using a box-corer to obtain granulometrics indices of sediment and biological sampling of infauna.

Prospecting Scomber scombrus and Trachurus trachurus eggs and adult catches to estimate egg production and fecundity of Scomber scombrus for joint international evaluation of spawning stock biomass of mackerel by the method annual egg production (MPAH) and production eggs Trachurus.
