Objective	1. Estimation of pelagic fish abundance in coastal waters of southern Europe using echo integration. 2. Mapping of the area of distribution. 3. CUFES continuous underway recording to estimate egg abundance. 4. Pairovet used to calibrate CUFES recordings and conventional station measurements. 5. Estimation of size-fractioned plankton biomass (CHN method). 6. Studying oceanographic and meteorological conditions and how they are related to distribution and abundance of adult pelagic fish eggs. 7. Hydrology: Characterization the thermohaline properties of continental shelf waters. Measuring vertical profiles of temperature, salinity and fluorescence at stations surface data acquisition (thermosalinometry, fluorescence and meteorology). 8. Plankton: Determining taxonomic diversity and biomass distribution patterns in different size classes of plankton (phytoplankton and zooplankton) in the study area.

Summary of measurements

-Acoustics: acoustic sampling was to be done in daytime on a sampling grid with radial legs 8 miles apart. A total of 1,998 nautical miles were covered, 977 on radials.
-Trawls: A pelagic trawl and a GOV semi-pelagic trawl were used. A total of 61 hauls were made.
-Hydrology and plankton: stations set on acoustic transects, 3 nautical miles apart (at night, on profiles coinciding with the acoustic ones). A total of 113 vertical profiles of salinity, temperature and fluorescence along 20 transects.
-Continous underway recording of eggs. CUFES pump used to get water at 3m deep. The CUFES (Continuous Underway Fish Egg Sampler) provided the horizontal distribution of eggs. A total of 370 samples were obtained.
