Abstract: Sturgeons are the most important fish in the Caspian Sea, but there are only a few reports about their parasite communities in the southern part of this sea. In this study, 102 samples of 3 sturgeon species, namely Acipenser gueldenstaedti (n = 78), A. nudiventris (n = 18) and Huso huso (n = 6), were caught from 3 geographical locations in the southwest of the Caspian Sea (Guilan Province, Iran) from April 1999 to February 2001. Eight worm species including 3 nematodes [Cucullanus sphaerocephalus, Eustrongylides excisus (L.) and Anisakis sp. (L.)], 1 cestode (Eubothrium acipenserinum), 2 acanthocephalans (Leptorhynchoides plagicephalus and Corynosoma strumosum), 1 digenean trematode (Skrjabinopsolus semiarmatus) and 1 monogenean trematode (Diclybothrium armatum) were found in A. gueldenstaedti, A. nudiventris and H. huso.
