Evaluating the fish parasitic fauna should constitute a major concern, especially in the climate change context because the parasites have a significant impact both on the natural fish population and the farm yield, economic viability, or sustainability. In this context, this study aimed to present the influence of water quality parameters upon the distribution and variety of parasites of 14 freshwater species, belonging to 5 systematic families: Cyprinidae, Percidae, Siluridae, Clupeidae, Esocidae. Parasitofauna analyses were performed through classic methods and the results were expressed as the prevalence of parasitic fauna and their intensity grades. Although the experimental groups have a similar environment, they present a distinct parasitofauna which shows a strong influence of the environmental factors upon its development. Adequate knowledge and periodic monitoring of the prevalence of parasites on the fish populations can have multiple implications and can be used as an indicator of anthropogenic impacts on other aquatic environments.
