Ziel der Reise / Objectives of Cruise:
Investigation of the catchability of trawls with regard to the catch of O-group cod. Investigations of spawning activities of cod in the Bornholm Basin and sampling of overies for estimating the fecundity. Catch of ripe cod and providing artifical inseminated eggs for ensuing rearing trials in a aquaculture laboratory. Investigations of the survival of flatfishes in the discard after a trawl catch. Estimation of the actual hydrologic situation on the fishery stations.
