Introduction. The interest in the development of pond and lake fish farming is occurring in the Rivne oblast recently, as well as fish transferring for acclimatization and ponds stocking. All this requires detailed investigation in order to prevent fish diseases and carrying out measures aimed at improving the quality and quantity of fish products. In this regard, considerable interest is the study of parasitic diseases of fish, since science-based prevention of disease is one of the most important measures to increase fish productivity.

The goal of the work. Investigate the intensity of distribution invasive of diseases commercial fish ponds of the Rivne oblast.

Materials and methods. Sources for the retrospective analysis of the spread of fish invasive diseases we used official reports of the Rivne Regional State Laboratory of Veterinary Medicine for 2013–2015 years. Results of a retrospective analysis formed the basis for our further studies on fish parasitic fauna in ponds of the Rivne oblast. For determination of fish invasion same species of carp family were studied: carp, white amur, crucian carp, silver carp, roach. Fish parasitological research were conducted by І.E. Bykhovskaya-Pavlovskaya (1985) and K.V. Sekretaryuk (2001).

Results of research and discussion. According to the research, ponds of Rivne oblast are disadvantaged by a number of parasitic diseases of fish. First of all, it should be noted that we detected protozooses. The highest indices of extent infestation are chilodenelosis, trichodiniosis, ichtyophthiriosis, apiozomosis. Among noted submitted helminthiasis the most significant are trematodoses, namely diplostomosis. The most common helminthological diseases of carp is monogeneidoses – dactylogyrosis and gyrodactylosis. Among cestodoses the most value for fish in the oblast have representatives of the Caryophyllaeidae family, which cause caviosis and caryophyllosis. Substantial damage for pond fish farming causing crustaceoses: ergasilosis, sinergasilosis, lernaeosis and argulosis. The intensity of infestation is usually low and clinical manifestation of diseases do not usually observed. However, the presence of these agents in the fauna poses a serious threat to the development of valuable commercial fish species such as carp, white amur and others.

Conclusions and prospects for further research. Indices of extent of invasion showed that epizootic situation in the farming ponds of the region characterized by widespread protozooses (chilodenelosis, trichodiniosis, ichtyophthiriosis, apiozomosis) helminths (diplostomosis, dactylogyrosis, gyrodactylosis, caviosis, caryophyllosis) and crustaceoses (ergasilosis, sinergasilosis, lernaeosis, argulosis). Further research will be aimed at a more in-depth study of the biology of pathogens in the region and selection of the means and methods for treatment and prevention of these diseases.
