New Host Record

An infection with a marine trematode, Tubulovesicula lindbergi (Layman, 1930) (Digenea: Hemiuridae), was discovered in a resident white sturgeon, Acipenser transmontanus Richardson, taken in the central Columbia River, Washington, USA. Tubulovesicula lindbergi is normally restricted to marine environs by virtue of essential (but still unknown) invertebrate intermediate hosts, but may occur in migratory fish that enter fresh water. Since hydroelectric dams on the Columbia are now effective barriers to the passage of sturgeon, it is postulated that T. lindbergi was transported into the river system by a maturing, anadromous teleost. After the postspawning death of the "transport" teleost host, the sturgeon presumably acquired the infection when scavenging. Consideration of basic synecological relationships supports the hypothesis. The white sturgeon is a new host record for T. lindbergi.
