Abstract

Ichthyoplankton material provides information on the species composition in an area of investigation and leads to a better understanding of the entire fish community. Since 1993 every year in May and/or June an ichthyoplankton survey in ICES-Subdivision 22 and 24 has been performed to sample the plankton community of fishery resources in the western Baltic Sea. One objective was to get signs of possible changes in the natural structures of this fish community. The time series derived from the Bongo-Net samples does not show a clear trend in larval densities. Values varied, but up to now samplings in the western Baltic Sea yielded only low mean densities. According to the kind of reproductive biology the fish species were divided in three major groups: • Fish species with a long developmental phase in the plankton community • Small short living species with benthic eggs and a reduced plankton phase • Guests without local spawning populations. Species could be identified, which were absent in the fish larvae catches of the western Baltic Sea in the 60s and 70s.
