New calibration tests between B/O Cornide de Saavedra and the B/O Miguel Oliver, by the results of the 2013 campaign Demersal, showing behavior too benthic.

Collection of data needed to estimate Abundance and biomass of species of commercial interest
-
The main objective is the collection of data that allow estimate the abundance, biomass and demographic structure of the species of commercial interest in the regulation area NAFO, until a maximum depth of 1500 m.

The Platuxa campaign has been carried out annually in the divisions 3NO of NAFO since 1995. The campaign has the following objectives: - Collection of data needed to estimate Abundance and biomass of species of commercial interest (Gadus morhua, Sebastes spp, Hippoglossoides platessoides, Reinhardtius hippoglossoides, Limanda ferruginea, Amblyraja radiata). - Sampling of stomach contents - Collection of hydrographic data with CTD SBE25. The information obtained during this campaign is used in the NAFO Scientific Council to assess fishery resources in the Bank of Newfoundland, of interest to the Spanish fleet; As well as in various Studies of a more biological and ecological character.

To estimate stratified abundances indices by age of hake, megrims and monkfishes. To estimate stratified abundances indices of commercial fish species (N. norvergicus, P. blennoides, H. dactylopterus, G. cynoglossus and rays). To estimate recruitment indices and spatial trends of younger ages of hake, megrims and monkfishes. To describe the spatial distribution patterns of demersal and benthic species of Porcupine. To collect data for the determination of biological parameters for the demersal species selected by DCF (Data Collection Framework).

Spanish Porcupine bottom trawl survey aims to collect data on the distribution and relative abundance, and biological information of commercial fish in Porcupine bank area (ICES Division VIIb-k). The primary target species are hake, monkfish, white anglerfish and megrim, which abundance indices are estimated by age, with abundance indices also estimated for Nephrops, four-spot megrim and blue whiting. Data collection is also collected for several other demersal fish species and invertebrates.
