Abstract
ntroduction. The actual problem of Rivne oblast fish farms raising carp is helminthiasis caused by trematodes (diplostomosis) and intestinal cestodes (caviosis and cariofilosis). Contaminated fish poses no threat to human health and life, but causes significant economic losses for hatcheries: fish is exhausted depleted, lagging behind in growth and development, loses weight and often dies. The average loss of fish production due to helminthiasis ranges from 15 to 10 %, while at invasion outbreaks mortality of underyearlings observes in over 50 %. The goal of the work. To investigate seasonal dynamics flow trematodes and cestodes infestations of carp in areas of its raising and to determine anthelmintic efficacy of the preparation “Ribolik” against these helminths. Materials and methods. Parasitological investigations were carried out under fisheries “Rovnorybhoz” of the Rivne oblast. The parasites species belonging we determined by “Determinant of parasites of freshwater fish fauna of the USSR”. We determined the effectiveness of modern anthelmintic preparation “Rybolik” (Brovafarma, Ukraine) against carp trematodes and cestodes helminths under fish farm production conditions. Results of research and discussion. The fish were infected in young age in ponds, where there are favorable conditions for intermediate hosts of trematodes and intestinal cestodes. Parasites reproduction increases rapidly in the summer, when the water temperature isappropriate. The peak of diplostomosis occured in September, when invasion extensiveness made 40 %, khawiosis in August with 39 % extensiveness of invasion, caryophyllidean tapeworms in September with 55,5 % extensiveness of invasion. Helminthological research of fish conducted on the 7th day after deworming showed that the recommended dose of therapeutic feedstuff with “Rybolik” in the amount of 1,5 %, against diplostomosis ensure efficiency in 75 %, khawiosis in 100%, caryophyllidean tapeworms in 100 %. Conclusions and prospects for further research. In fish farm “Rivnerybhosp” ponds the peak of carp diplostomosis occured in September with 40 %extensiveness of invasion, khawiosis in August with 39 % extensiveness of invasion, caryophyllidean tapeworms in September with 55,5 % extensiveness of invasion. Studies indicate that the use of therapeutic feedstuffs, which included anthelmintic preparation “Rybolik” provides high efficiency against monoinfestation and mixed infestations of carp.
