Objective	The main objective is to understand the ecology of two target species, anchovy and sardines, by characterizing the environment which is associated with their distribution. The environmental study covered the quality and circulation of water masses, the first trophic levels, zooplankton and the multi-species community of adult fish. The pelagic ecosystem was mainly addressed through a "size structure" approach. The medium-term aim is to understand the mechanisms determining the multi-species community dynamics of fished pelagic species and monitor any effects on the recruitment of a few species. This falls under the DRV/RH "resource variability" project and the PNEC project.

Summary of measurements

-Acoustic exploration using 4 frequencies (12, 38, 49 and 120 kHz) to study the horizontal and vertical distribution of fish and establish abundance indices for the fished pelagic species (target species were sardine & anchovy).
-Pelagic trawling to identify echoes and biological samples taken on adult fish.
-Bottom trawling to identify echoes and biological samples taken on adult fish.
-Continuous pumping at the surface using the CUFES system to count fish eggs.
-Vertical plankton fishing (PAIROVET) to calibrate fish egg distribution over the entire water column and CUFES surface counts.
-The continuously pumped water was analyzed to measure nutrients: nitrates, nitrites, ammonium, silicates (samples frozen on board for later analysis) and phosphates were analyzed on board.
-Chlorophyll A and pheopigments were measured on board using filtration and the qualitative composition of plankton communities and size structures were analyzed for phytoplankton, microzooplankton and zooplankton).
-Light penetration and natural fluorescence profiles (PNF300), reflectance and suspended matter measured.
-Temperature, salinity and fluorimetry profiling of frozen samples and current measured using ADCP.
-Plankton caught using triple WP2 net (200 micron) to analyze the communities and carbon, nitrogen, lipids and proteins in zooplankton were measured.
