Summary of measurements

-Acoustic exploration (acquisition and storage of signals on 5 frequencies) for the distribution and abundance of pelagic fish species, mainly anchovies and sardines.
-Pelagic (or bottom, or mesopelagos) trawl fisheries to identify target species and characterize resources (size distributions, demographics, biological characteristics).
-Egg counts using surface pumping with the CUFES system to determining spawning zones.
-Taking samples on adult sardines and anchovies for genetic analyses to distinguish whether different "groups" exist in the Bay of Biscay.
-Catching plankton to characterize the biotic environment of small pelagic fish populations (biochemical indices descriptors of zooplankton dynamics).
-CBT stations and continuation observation to describe hydrological conditions by associating available satellite photos and circulation modeling results following the model developed by P. Lazure.
-Characterizing the diversity and abundance of micro-zooplankton as well as other plankton compartments in order to evaluate the structure of the plankton food web.
-Identification and visual counts of cetaceans and birds present in the area to describe higher predators in the pelagic ecosystem of the Bay of Biscay.
-Density column used to study vertical migration of eggs in the water column.
