Summary

In a population of copepods (Cyclops strenuus abyssorum), with a naturally high prevalence of infection with procercoids of Diphyllobothrium spp., no difference in body size was found between infected and uninfected hosts. However, a significant reduction in the reproductive capacity of infected females was observed, 87% of uninfected females having developed eggs in their gonads and sacs compared with 21% of infected females. The feeding rate of infected copepods was relatively high soon after infection occurred, but gradually decreased to less than half that of uninfected animals. Respiration rate was also lower in infected copepods. Infected copepods showed reduced motility and impaired escape responses, which is likely to make them more susceptible to predation.
