EFFECT OF ENVIRONMENTAL FACTORS ON COMPOSITION, NUMBER AND DISTRIBUTION OF GOBIES IN THE WESTERN PART OF THE NORTH CASPIAN SEA
Abstract. Information about abudance and distribution of 8 species of Caspian gobies (Neogobius melanostomus, Neogobius kessleri, Neogobius syrman eurystomus, Neogobius gymnotrachelus, Neogobius caspius, Proterorhinus marmoratus, Bentophilus sp.) is given. A method of trawling (number of gobies / on...

Information about abudance and distribution of 8 species of Caspian gobies (Neogobius melanostomus, Neogobius kessleri, Neogobius syrman eurystomus, Neogobius gymnotrachelus, Neogobius caspius, Proterorhinus marmoratus, Bentophilus sp.) is given. A method of trawling (number of gobies / one o'clock trawling) was used. Hydrological and hydrochemical changes in the Caspian Sea influence the distribution and abudance of goby fishes in the western part of the North Caspian Sea. Changes of species composition and distribution depended on the lowering in the sea level, increase of salinity, temperaturebackground. The maximal abudance of gobies in 2010 were as in previous years in the highly productive waters (western part), where was the fattening of sturgeons, semi-anadromous and marine fishes. Concentration of gobies is decreased in less trophic waters (eastern part) of the Northern Caspian Sea. |
