Influence of fish personality on infection rate is almost not studied. In the experiments on the young-of-the-year Oncorhynchus mykiss and cercariae of a trematode Diplostomum pseudospathaceum we tested the hypothesis that infection rate differs between more and less active (“bold” and “shy”) fish. Will individual differences in infection persist upon re-infection? Fish serve as a second intermediate host for this trematode. A positive correlation was found between the results of consecutive infections. Accumulation of parasites with successive infections leads to an aggregated distribution of D. pseudospathaceum among the hosts, affecting individual fitness and polymorphism in fish populations. Persistent individual differences in parasite burden among fish and, as a result, vulnerability for predators confirms the role of parasites as an important factor of natural selection.

Parasite transmission in aquatic ecosystems under temperature change : effects of host activity and elimination of parasite larvae by filter-feeders Gopko, Misha; Mironova, Ekaterina; Pasternak, Anna; Mikheev, Victor; Taskinen, Jouni (Wiley-Blackwell, 2020)A moderate raise in temperature was suggested to enhance the impact of parasites on aquatic ecosystems. Under higher temperatures, poikilothermic animals (e.g. fish) increase their activity, which can result in a more ...
Negative associations between parasite avoidance, resistance and tolerance predict host health in salmonid fish populations Klemme, Ines; Hyvärinen, Pekka; Karvonen, Anssi (The Royal Society Publishing, 2020)Genetic variation in defence against parasite infections is fundamental for host–parasite evolution. The overall level of defence of a host individual or population includes mechanisms that reduce parasite exposure ...

Mironova, Ekaterina; Gopko, Mikhail; Pasternak, Anna; Mikheev, Viktor; Taskinen, Jouni (Cambridge University Press (CUP), 2022)Temperature and intraspecific competition are important factors influencing the growth of all organisms, including parasites. The temperature increase is suggested to stimulate the development of parasites within poikilothermic ...
