Abstract
Diplostomum sp. is a trematode parasite that infects aquatic snails, e.g. Lymnaea stagnalis (Gastropoda: Lymnaeidae), fish, and fish-eating birds. Ponds and lakes (n = 28) located in Finland between latitudes 61°45′N and 65°30′N were sampled for L. stagnalis, the first intermediate host for Diplostomum sp. L. stagnalis were found in 22 sites out of 28, and Diplostomum sp. in 10 of the 22 snail populations. Among the L. stagnalis populations that were infected by Diplostomum sp., the mean prevalence was 12.8%. Diplostomum sp. occurred in only one out of the seven L. stagnalis populations in four large lakes, but in 9 out of the 16 L. stagnalis populations in small lakes. In the pooled data, a positive correlation (r s = 0.427; P = 0.047; n = 22) between L. stagnalis density and Diplostomum sp. prevalence was found. The results suggest that Diplostomum sp. is fairly common in L. stagnalis populations in small lakes but rare in large lakes. Furthermore, although trematode parasites, in general, should have a negative effect on snail population density, the study indicates that the relationship between host density and parasite prevalence may greatly differ for individual trematode species, such as Diplostomum sp.
