Research of the species composition of the coastal ichthyocenosis of the Baltic sea within the Kaliningrad coast

The article is devoted to the characteristics of the species composition of the coastal ichthyocenosis of the Baltic Sea in subdistrict 26 within the Kaliningrad region. Catches data on in the coastal part of the sea at depths of less than 20 m for the period 2006–2023 were used. Fishing was carried out using a set of fixed nets with a mesh size from 10 to 80 mm, a cast net and drag nets with a mesh size from 10 and 5 mm, respectively. These fishing gears allow to catch all fish species and all size groups. Totally, 1256 catches in different seasons and in different areas were carried out. The coastal ichthyocenosis are presented 32 fish species from 21 families. The targets of fishing are 90,6% of all species; 25,0% of which are actually fished, the frequency of occurrence of these species is 59,3%. The other species are non-target of fishing. In general, more than 80% of species were presented sporadically in the ichthyocenosis and their frequency of occurrence does not exceed 10%. The results of the research can be used to optimize fisheries and assess the impact of various types of economic activities on coastal ichthyocenosis.
