Summary of measurements

-Acoustic prospecting (4 frequencies signal) 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).
-Counting eggs using surface pumping with the CUFES system to determine 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 to describe 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.
-Setting up an on-board hatchery for anchovy and sardine egg to study the contribution of micro zooplankton and phytoplankton to fish larva nutrition.
