Parasite-Resistant “Super” Trout

March 24, 2005

Geneticists at Utah State University are testing various trout species to determine which of the fish are most resistant to the whirling disease parasite. A strain of rainbow trout found in Montana has shown a stronger resistance to the parasite than Utah’s state fish, the Bonneville cutthroat. Researchers plan to create a brood stock to test in whirling disease-infected waters.
