Summary of measurements |
- -Samples taken using GOV wide opening vertical trawl: calculating abundance indexes for commercial species.
-Acoustic prospecting: logging data from ER60 and ME70. -Sampling of larvae: calculation of larval abundance indexes for herring and sprat using MIK larva net. Stations performed at night. -Egg sampling: Characterization of winter spawning zones and habitats in the North Sea. Sampling using CUFES (Continuous Fish Eggs Sampler). -Sampling of zooplankton and phytoplankton: Studying hydrological, phytoplankton and zooplankton compartments. -Observation of seabirds and marine mammals in the English Channel. -Characterization of seabed and benthic species; underwater videos.
