First paragraph of introduction: On 20 July 2004 a single Asian tapeworm (Bothriocephalus acheilognathi) was collected from the intestine of a roundtail chub (Gila robusta) in the Yampa River in Dinosaur National Monument in northwestern Colorado. This fish (274 mm TL) was collected at river mile 24 and dissected in the field. A single tapeworm was removed from the intestine and preserved in ethanol. The tapeworm was later identified in the laboratory as B. acheilognathi by its characteristic arrow-shaped scolex (Poole et al. 1984). This is the 1st recorded incidence of Asian tapeworm infecting fish in the Yampa River drainage. Published in Western North American Naturalist, volume 65, issue 3, on pages 403 - 404,...

Examination of gastrointestinal tracts of native cyprinids from the Little Colorado River (LCR) in Grand Canyon, Arizona, 1990-1994, revealed varying rates of prevalence and infrapopulation levels of Asian tapeworm (Bothriocephalus acheilognathi). Mean prevalence was 28% (range 0-78%) in humpback chub (Gila cypha) and 8% (range 0-46%) in speckled dace (Rhinichthys osculus), with infrapopulations as high as 46 and 28, respectively. We also note Asian tapeworm infection of nonnatives common carp (Cyprinus carpio), fathead minnow (Pimephales promelas), and plains killifish (Fundulus zebrinus) from the LCR. Reported pathogenic and chronic effects of this cestode to its definitive hosts add concern for the status of...
