The First Record And Description Of Chaetogaster Limnaei Von Baer, 1827 (Naididae, Oligochaeta) On Huso Huso Fry In Serbia
HELMINTHOLOGIA(2000)
摘要
Oligochaeta Chaetogaster limnaei has been described in the literature exclusively as a commensal or semi-parasitic species inhabiting mantle cavities, pulmonary and kidney tissues of many freshwater genera of the Pulmonata (Gastropoda).During our studies the parasite was detected on the body of beluga fry (Huso huso, Acipenseridae, Pisces). Apart from its record on the new host, it is important to point out that this parasite provoked injuries of the beluga fry epithelia by its mouth apparatus. Small wounds appeared on contact spots leading the fry to an extinction. Therefore, it is our assumption that this is the first record of Chaetogaster limnaei as ectoparasite on the fry of beluga, which has not been described in the literature so far.
