Background: Water bodies in the Ustya River basin (a small river in the Prypiat River basin, a left-bank tributary of the Goryn River) are used by local population for amateur and sport fishing. Objects of fishing are common and numerous representatives of the ichthyofauna: Prussian carp (Carassius gibelio Bloch) and common roach (Rutilus rutilus L.). The caught fish is not always thermally processed, which is dangerous for a number of reasons. In particular, there is the danger of infecting humans and domestic animals by parasitic organisms; in addition, the poor quality of surface waters affects the quality of fish meat.

Aim: to study the relationship between indicators of the ecological state of surface waters and indicators of parasite crustaceans population on widespread fish species.

Material and methods: Hydrochemical and ichthyoparasitological studies were carried out in 2013-2019. Water quality was evaluated according to the method of ecological assessment by integral ecological index (Ie), which includes three block indices – salt indicators (I1), trophic-saprobic indicators (I2), specific indicators (I3). Three parasitological indices were used: prevalence (P), intensity of infection (II), and mean abundance (M). To clarify the relationship between indices a correlation analysis was carried out.

New findings: Parasitological studies showed that the prevalence of argulosis invasion of Carassius gibelio is higher than that of Rutilus rutilus – 8.04 vs. 7.88%. On the contrary, intensity of infection and mean abundance are higher in R. rutilus – 1.63 vs. 1.24 and 0.16 vs. 0.13, respectively. Analysis established the negative correlations for all parasitological indices: strong with the trophic-saprobic block index (I2), and weak or absent with the salt block index (I1) and specific indicators block index (I3). The increase in the trophic state of water bodies is associated with the decrease in fish morbidity with argulosis.

Keywords:    water quality, ecological assessment, ecological index, argulosis, parasitological indices, correlation analysis.
