  Gila, generally including species referred to as western chubs, represents a taxonomically diverse group and currently spans most of the nonglaciated regions in western North America (). Gila has been proposed to be an old group, with a fossil record extending from the Miocene to the Pleistocene. The oldest known fossil assigned to Gila (Gila turneri, authority Eastman ) dates from the   The Cowhead Lake tui chub, Gila bicolor vaccaceps (Warner basin, south-central Oregon), was proposed for federal listing on Ma The proposed rule precipitated negotiations between private landowners, Bureau of Land Management (BLM), California Department of Fish and Game (CDFG) and the U.S. Fish and Wildlife Service (USFWS)  Web view.   Introgressive hybridization and genetic differentiation of endangered Owens tui chub populations.

For the State of the Salmonids II: Fish in Hot Water report, the following methods were used to assess the status of all 32 kinds of salmon, steelhead, and trout in California.. SELECTION OF SPECIES. The research team used species, subspecies, Evolutionary Significant Units (ESUs), or Distinct Population Segments (DPSs) - taxonomic categories already

Tui chub in Chewaucan Basin, however, were distinct and thought to be another allopatric species, although the genetic similarities to Goose Lake and Warner Valley tui chub compared with other This interpretation included the Gila Chub G. intermedia and Headwater Chub G. nigra, both confined to the Gila River drainage of the lower Colorado River basin in Arizona and New Mexico, and the Roundtail Chub G. robusta, a much more wide-ranging species occurring throughout most of The status of Pacific salmon populations has been of increasing concern for many decades, with many populations now under legal protection. The causes of their declining status are manifold and untangling them has been difficult due to the complex life histories, which involve migrations among freshwater, estuarine, and marine :// FISHES WHICH HAVE ACHIEVED LASTING SUCCESS American shad, Alosa sapidissima (Wilson) A portion of the history of this fish, native to the Atlantic Coast of the United States, the largest member of the herring family in North America, the first of its family to be propagated, and the first aquatic species to be formally introduced into California, has been related in the Foreword.
