Abstract

Acanthobdella peledina is a 0.9–3.3 cm long fish parasite living mainly on the skin of salmonid fishes in Fennoscandia. It attaches to the body of fish, feeding on blood, skin, fins and flesh. A. peledina parasitizes eight species or ecotypes of fish in Finland: Arctic charr (Salvelinus alpinus), brown trout (Salmo trutta), lake trout (Salvelinus namaycush), grayling (Thymallus thymallus), vendace (Coregonus albula), common whitefish (Coregonus lavaretus), humpback whitefish (Coregonus pidschian) and blaufelchen (Coregonus wartmanni). It has been found in 18 locations in Finland, including 11 lakes, 6 rivers and one closed fish farm. Infection rate was up to 33 % of Arctic charr in Lake Pitsusjärvi. Morphological drawings of A. peledina done under a stereomicroscope are presented. Parasites are not harmful to humans and the fish can be cleaned and cooked as usual.
