Prevalence of infection of Acipenser persicus broodstocks with internal parasites in the south-west Caspian Sea

Abstract

A survey of parasitological infections of Acipenseridae fishes in the southern parts of the Caspian Sea were done from 2002 to 2004. Altogether, 338 brood stocks of Acipenser persicus were examined. In the laboratory, the weight and length of the fishes were measured and after dissection presence of different parasites in the fish was examined. According to the results of this study, during three years of examinations, six different parasites were detected. These parasites were Cucullanus sphaerocephalus, Skrjabinopsolus semiarmatus, Eubothrium acipenseinum, Corynosoma strumosom, Leptorhynchoides plagicephalus, and Amphilina foliaceae. The prevalence and mean intensity of infection with Gusullanus sphaerocephalus and Skrjabinopolus semiarmattim were the most.
