DISTRIBUTION, BIOLOGY AND POPULATION STATUS OF BENTO-PELAGIC FISH SPECIES IN THE AREA OF THE SEA CHANNEL OF CARGO TRANSPORTATION IN THE NORTH-EAST CASPIAN

Abstract

In modern conditions, the Caspian Sea is experiencing intense anthropogenic pressure due to increasing work on the development and production of oil and gas, as well as a result of urbanization, industrial and agricultural activities. This paper provides a brief overview of the biology of goby fish in the study area, distribution, and biological role in trophic chains. Based on the materials of the bottom trawl survey in the research area, the spatial distribution and some features of the biology of fish of the Gobiidae family are considered. Goby fish are an important food link in the ecosystem of the Caspian Sea, acting as food objects for many valuable fish species, and at the same time, consuming a huge number of organisms of aquatic organisms, enter into competitive relations with other fish.
