RARE COMPONENT OF THE FISH FAUNA OF THE 'SULINSKY' NATIONAL LANDSCAPE RESERVE

Abstract

Maintenance of biological diversity is the main task of modern biology. At the legislative level, Ukraine has pledged its support in ratifying the on the conservation of biological diversity. As part of the implementation of environmental policy in Ukraine preservation of rare fish fauna component is the most problematic aspect. The basic conservation lists acting in Ukraine are: Red List of threatened animals of the International Union for Conservation of Nature, Ukrainian Red Book, Annex III of the on the Protection of wildlife and natural habitats, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, CITES, Washington, 1973. On the territory of Sula Bay located two objects of nature reserve fund - a landscape national reserve and National Park Nizhnesulsky that emphasizes the importance of this area for fish fauna reproduction. Its territory are spawning areas for almost all lower and middle parts of the Kremenchuk reservoir, ensuring more than half of total commercial catch of the Dnieper cascade. The article describes the species composition of the fish fauna, introduced in protected lists of different levels. The existence of seven such species was established. They belong to four families: four species - for cyprinids and one each - to sturgeon, loaches and catfishes. But we must remember that the priority activities should concern species with the highest conservation status. At the same time, four of them are only protected by Annex III of the on the Protection of wildlife and natural habitats as poorly studied. These species require a more thorough study and not necessarily threatened with extinction. Remaining three species are under a real danger of extinction and are protected by the IUCN Red List and Ukrainian Red Book. Starlet also protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora, CITES. Environmental authorities should focus attention on their protection and restoration of abundance.
