Description 
Summary

The main aim of this project was to determine the vertical distribution of pelagic eggs and larvae of fish in the Bornholm Basin and the influence of hydrological parameters on their distribution. Samples were collected during the cruises on RV 'Baltica' in 1993, 1994 and 1995. During the 1993 cruise (22 Jul-07 Aug) three transects were chosen, and during the other cruises (17-28 Aug 1994; 01-09 Sep 1994 and 20-29 Jun 1995) one transect for each cruise was covered. Along these transects the stratified hauls with a Multinet were taken at depth range from 0 to 80m (20-minute hauls, repeated five times in each 10-metre depth layer). The Multinet consisted of 5 nets of 0.25 m**2 opening and 300 microm mesh size; the last net could not be closed. The hydrological parameters were recorded with a CTD probe coupled with the sampler. Samples were preserved in 4% borax-buffered formaldehyde. The eggs and larvae were sorted out by species and the total number of eggs per species was estimated.
