Sever occurrence of Branchiobdella kozarovi Subchev, ۱۹۷۸ in cultured freshwater crayfish

Freshwater crayfish of Aras dam, is one of the most important economic aquatic animals of Iran. Three specimens of Astacus leptodactylus maintained in a static culture condition in a concrete pool were examined for the occurrence of Branchiobdella sp. We reported for the first time the severe intensity of Branchiobdella kozarovi (mean=۱۳۵۹.۳±۴۳.۶) isolated from the gills and exoskeleton of A. leptodactylus maintained in static culturen. All heavily infected specimens died. A culture system with non-circulating water is not suitable for freshwater crayfish maintenance.
