General characteristic of ichtiophauna of protected aquatories of small and middle rivers of Dnipropetrovsk region
AbstractModern Ukrainian statehood development strategy provides for the integration of all its components in the institutions of the European structures. Under this strategy, Ukraine has ratified all the most common in Europe and worldwide convention for the conservation of rare species of animals, including fish. This List of International Conservation of Nature (IUCN), the Berne Convention, the Ramsar Convention. Adopted domestic security lists: Red Book of Ukraine, Dnipropetrovsk region Red Book. In the above context, the aim of the present study was to conduct an inventory summary of the ichthyofauna of small and medium-sized rivers Dnipropetrovsk region over the last thirty years, to identify the main patterns of distribution and distribution of fish over a network of protected areas reserved.Complex ichthyological studies were conducted from 1983 to 2013. the waters of the largest small and medium rivers tributaries. r. Dnipro (Dnipro reservoir): r. Samara, r. Wolf, r. Orel, r. Mokra Sura, r. Ingulets, r. Bazavluk, as well as the offshore reservoirs constructed within the boundaries of their waters.These studies established the following.Summary list of fishes of small and medium-sized rivers are 55 species of 58, set in the Dnipropetrovsk region. Thus the widespread belief of complete degradation of the fish community of small and medium-sized rivers are extremely exaggerated. Small and medium-sized rivers also continue to play a crucial role in the conservation of rare and endangered species of fish in Ukraine, Europe and the world in general. Within the reserved waters identified 24 fish species (44% of total species), having an international protection status (IUCN, Berne Convention, the Ramsar Convention). It lists the Red Book of Ukraine and Red Book of Dnipropetrovsk region holds 19 species of fish. Determined that the major role in preserving the original and rare fish fauna play open waters of small and medium-sized rivers with an area of open mirror 75 % and above as well as small and medium-sized reservoirs located on these rivers. Here identified 45 of the 55 recorded species (83 % of total vidovgo of fish).It was established as a result of adaptive processes occurring in areas of direct intensive pollution in particular mine waters inhabited by fish, with an international, domestic and regional conservation status: char mustachioed (Barbatula barbatula L., 1758), river burbot (Lota lota L., 1758) ordinary minnow (Gobio gobio L., 1758). Revealed that more than 50 % of the species composition of fish that have protected status, live within the boundaries established loklitetov not singly, but show the numerical parameters are more inherent mass typical species.A concept of the conservation of rare species in the region, which is as follows. In the absence of the ability to effectively protect rare species from the state, the optimization process of preservation of rare and endangered species should be based solely on scientific managing economic and recreational activities in the leased waters. Moreover, experience shows in favor of educational outreach to tenants in the context of very high prestige preserve fish with conservation status, living in rented their reservoirs.
