ABSTRACT

The investigation was undertaken to analyze the species composition, abundance, and length distribution of fish assemblages inhabiting different littoral habitats in Lake Kosno. The fish were caught during the day and at night with multi-mesh gillnets in July, September, and November 2006. The fish caught belonged to three families and eleven species. Perch, Perca fluviatilis L., and roach, Rutilus rutilus (L.) were represented most abundantly. Significant variability was noted in the abundance of fish in subsequent months. In July the abundance of fish in the littoral zone was nearly four fold higher than in September and November. Neither the time of day nor the habitat type had a significant impact on the abundance of the fish assemblages, while the time of day and the littoral zone type did impact the size of the fish caught. The application of Nordic multi-mesh gillnets to the study of the ichthyofauna composition in the littoral zone of Lake Kono permitted determining the impact the type of littoral zone and the time of day had on the species composition and length distribution of the fish assemblages.

Key words: fish assemblages, littoral zone, Nordic multi-mesh gillnets, size structure.
