SUMMER FOOD HABITS AND TROPHIC OVERLAP OF ROUNDTAIL CHUB AND CREEK CHUB IN MUDDY CREEK, WYOMING
The Southwestern Naturalist, 2006Abstract Native fishes of the Upper Colorado River Basin have experienced substantial declines in abundance and distribution, and are extirpated from most of Wyoming. Muddy Creek, in south-central Wyoming (Little Snake River watershed), contains sympatric populations of native roundtail chub (Gila robusta), bluehead sucker, (Catostomus discobolus), and

Spawning and Culture of Humpback Chub
The Progressive Fish-Culturist, 1982Abstract During 1981, humpback chub (Gila cypha) were spawned and cultured at Willow Beach (Arizona) National Fish Hatchery. This species is listed as endangered by the U.S. Fish and Wildlife Service. Seventeen wild females ovulated after injection with 4 mg acetone-dried carp pituitary per kilogram of body weight. Eight females were stripped manually,

Steroidogenesis in Ovarian Follicles of Chub Mackerel, Scomber japonicus
Zoological Science, 2005We incubated different radiolabeled steroid precursors with intact chub mackerel ovarian follicles to clarify the synthetic pathways of steroid hormones during vitellogenesis and following final oocyte maturation (FOM). During vitellogenesis, estradiol-17beta (E2) was synthesized from pregnenolone via 17-hydroxypregnenolone, 17-hydroxyprogesterone ...

The American Midland Naturalist, 2000
Abstract Spawning behaviors were filmed and observed in the nest-building minnows, the bluehead chub, Nocomis leptocephalus, and river chub, N. micropogon. Analysis of videotapes exposed previously unreported behaviors (e.g., female retroflexure) and a precise sequence of male-female interactions that coordinated a successful spawn.

Molecular Ecology Notes, 2002
AbstractPrimers were developed for 17 microsatellite loci from an enriched (GATA)n library from DNA from Gila bicolor obesa. These primers were tested for cross‐species amplification in Gila bicolor snyderi, Gila orcutti and Gila coerulea.

Acute Toxicity of Carbofuran to Adult and Juvenile Flathead Chubs
Bulletin of Environmental Contamination and Toxicology, 1999Cross et al. (1986) and Pfleiger and Grace (1987) reported that flathead chub (Platygobio gracilis) populations have decreased by as much as 98% over portions of their historical range. The causes of these declines are not well understood; however, degraded habitat and water quality are suspected (Lee et al. 1980).

Artificial reproduction of two different spawn-forms of the chub
Reproductive Biology, 2010The aim of this study was to compare, under controlled conditions, reproduction results of cultured and wild stock of the chub. Wild fish spawned only once a season whereas the cultured stock spawned at least two times. In the multiple-spawn stock, fewer fish spawned and the weight of produced oocytes was reduced compared to the single-spawn stock ...

Didymozoids in Muscle of Atlantic Chub Mackerel (Scomber colias)
Acta Parasitologica, 2019Digenean trematodes of the family Didymozoidae are tissue parasites that are particularly common in scombrid fish. These parasites can reduce the commercial value of fish, especially the ones occurring in the muscle.In the present study and for the first time, we report the occurrence of didymozoids in muscle tissue of Atlantic chub mackerel (Scomber ...

Conservation Genetics, 2008
The Cow Head Tui Chub, Siphateles thalassinus vaccaceps, is restricted to the small Cow Head basin in far northeastern California and northwestern Nevada. Using microsatellite DNA loci, we found extensive genetic variation among tui chub populations in the Cow Head and surrounding basins of the northwestern Great Basin.
