Main objectives: assesment and maping of spawing biomass of blue whiting by ecointegration, characterization of the hidrologic conditions of the surveyed area.

Stoca-F is a specific part of the STOCA project to do maintenance to the "ESPEE" mooring of Espartel (Gibraltar), verifing it´s sensors with the readings of a CTD and replacing batteries.

Main targets of PECAN 1602 are: - Setting-up of R/V Ángeles Alvariño as acoustic-fisheries prospecting vessel. - Optimizing sampling design for the systematic study and abundance estimating of Canary Islands pelagic species. - Using echo integration as a method to estimate Canary Islands pelagic species abundance.

The main aim of the Triennial surveys is to estimate the spawning stock biomass of mackerel and horse mackerel applying the Annual and Daily Egg Production Method (AEPM and DEPM). The method relates the number of freshly spawned eggs found in the water column to the number of female having produced these eggs. Knowing the fecundity of the females and the sex ratio provides an estimate for the spawning-stock Biomass. In the frame of the ICES WGMEGS,AZTI is in charge of sampling the area of the Bay of Biscay. Sampling consist in collecting plankton samples to identify and stage the mackerel and horse mackerel eggs. Environmental parameters: At each station profile of sea temperature and salinity are recorded.
