-
Abundance indices, distribution patterns and faunal assemblages of demersal species in the northern coast of Spain (Atlantic Galician shelf and Cantabrian sea shelf), together with the possible driving factors of their distribution
-
Study of strategies to reduce discards and unwanted species: selectivity and survival in trawling in Cantabrian-Northwest zone.
-
Impact of exploitation of mineral resources on the deep-sea ecosystems (MIDAS project)

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.

Set up techniques of circalittoral benthic habitat study of sedimentary seabeds, including identification and cartography of habitat and characterization of benthic communities, aiming to develop MSFD indicators.
