Ziel der Reise / Objectives of Cruise:

The cruise was conducted to study recruitment mechanisms in the early life history of mackerel, horse mackerel, and cod. Sampling was aimed at o-group juveniles. Specific objectives were: 1) Examine the overall horizontaldistribution of o-group juveniles in the sampling areas. 2) Analyze the vertical distribution of o-group fish within the upper 200m of the water column. 3) Examine feeding periodicity of o-group juveniles.
