Scientists have conducted ichthyological studies in the reservoirs of the Chornobyl radiation-ecological biosphere reserve within the framework of the Chronicle of Nature. The results showed that the species composition of fish here is slightly different from other reservoirs of the region.
19 species of fish were identified, mostly typical of the area. At the same time, a much lower number of invasive foreign species, which are much more in neighboring reservoirs. In particular, the reserve did not record any individual of the Amur Chebachko or sunshine, and the number of rattan and the crucian silver was minimal.
Scientists explain this with a relatively natural state of reservoirs and stability of ichthyocenoses. In unchanged reservoirs, stable ecosystems are formed, where foreign species are difficult to take root.
Research is of particular scientific importance, because there is no economic activity in the exclusion zone, nature preserved and a constant radiation background. This creates a unique environment for observations of changes in fish life in almost natural conditions.
Regular conducting of such studies will help to better understand the dynamics of species composition, the role of reservoirs in preserving rare species and the processes of recovery of aquatic fauna without human intervention. Such observations are important for preserving biodiversity in the radiation area.
Although it is too early to draw final conclusions as a result of one expedition, scientists hope that research will be continued and expanded.
