A non-native oligochaete, Bratislavia dadayi (Michaelsen 1905), is recorded from a water body of the cooling system of the Khmelnitsky Nuclear Power Plant (Ukraine). This is the first registration of this species in the central part of the European continent, far from sea and river navigable waterways. The only previous record of B. dadayi in Europe had been from a Belgian estuary. The occurrence in samples taken over several years, and the presence of sexually mature individuals in the Ukrainian population indicate the worm’s successful naturalization in the new habitat. In this paper, we analyze the species’ morphology and abundance in the Ukrainian population and discuss its ecology, current and potential distribution.

In countries like India there is always a scarcity for fresh water along with it polluting the available fresh water sources is a major threat. The major fresh water bodies are affected by eutrophication. It is the phenomenon in which algae forms a layer above the water surface and does not allow the sun light to enter into the water body. Due to this reason organisms which is present in the water body gets affected and the ecosystem gets damaged. The algae which are taken from the water bodies is dropped as waste in garbage or let to dry out on roads. “One man’s waste is other man’s treasure” so instead of wasting the collected algae, the algae can be used to prepare a dye which can be used to dye clothes for different uses. The collected algae are used as a raw material in an algal dying machine where the processes carried out are cleaning, drying the algae, grind it, boil them with water and other essentials, filter the residue and finally filtrate will be used to print on cloth.

The water quality of the Szarvas-Békésszentandrás Dead Körös is generally meso-eutrophic, and meso-saprobic. However, particularlyunder higher temperature conditions, the water body may change toward the eutrophic state, even algal blooms could be observedpreviously.The present measurements were conducted during a two week period, twice a day. Three water samples were taken horizontally, fromthe surface, bottom and the middle of the water body. The samples were examined in situ. The oxygen content, the temperature, the pH andthe conductivity were measured by potentiometric methods.Increasing pH was detected in correlation to the temperature, which indicated a rising photosynthetic activity. Also, the O2concentration showed high variations, especially, when the fresh water supply from the river was stopped, due to a small flood in the riverKörös.These results indicate the increasing eutrophication processes in the deadarm, and the high load and instability of the ecosystem.
