Abstract

Diplostomum spathaceum is a digenean parasite with an indirect life cycle. Its mature stage
lives in gull's intestine, cercariae in snails (Lymnaeidae) liver and metacercariae stage in
piscine, amphibian, and mammalian eyes. Notice that penetration of cercariae into skin and
eye cause lesions which cause susceptibility to secondary infections, appetite loss due to
infections, blurry vision, and disability in hunting and feeding on fish. It, therefore, plays an
important role in aquatic health. During this study, prevalence of Diplostomum spathaceum
infectious in 240 introduced and endemic fishes of water resources in West Azerbaijan
province were studied from spring 2008 to winter 2010. The results indicate that 58/30 % of
fish (140 fish) showed infestation with this parasite which presents a high rate of infestation in
the fishes in these water resources.
