Description 
Summary

Fish egg and larval surveys are carried out to map spawning grounds and to derive information on the adult spawning stock. FEAS are part of an international consortium of eight European countries that run the international mackerel and horse mackerel egg surveys every three years. At each station the GULF sampler is towed on a v-shaped profile to within 5m of the bottom, or a max depth of 200m, whichever is greater. Each file has station ID, time, date, position, sample and bottom depth, water temperature at 5m, 20m, 50m, 100m and max sample depth where appropriate, salinity at 20m, volume of water filtered during the tow, and Stage 1 egg counts for mackerel and horse mackerel.
