Ziel der Reise / Objectives of Cruise:

Target species are demersal fish species, mainly Baltic cod and flatfish species (flounder, plaice, dab, brill and turbot). The main aim is to determine the year-class strength of the target species. Target data are abundances, weight and length distributions of all fishes and length-weight-age-sex-maturity-feeding-parasitism data of commercially important species as well as hydrographic data (temperature, salinity and oxygen). Furthermore, abundance, weight and length data are collected for all fish species caught. The collected data are stored in a national SQL database and submitted to the ICES DATRAS database. In addition, marine litter and different biological samples (e. g. stomachs, livers, DNA, etc. from target species) are sampled for national and international studies. The survey is conducted annually in March-April and in October-November.
