Monthly survey to study thermohaline and biological characterization of water masses in the East-North Atlantic.
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.
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.
