Article
Full-text available
While the desert ecosystem is highly dependent on the water resources that sustain it, the Fish Slough spring complex is an arid, spring-dependent wetland undergoing a multidecadal decline in spring outflow. This evaluation updates the source water forensics of the Fish Slough Spring complex, a substantial spring complex in the northern Owens Valle...

The Mohave tui chub (Siphateles bicolor mohavensis) is an endangered cyprinid fish endemic to the Mojave Desert region of southeastern California, USA. Here, we describe the complete 16,607 base pair (bp) mitochondrial genome of S. b. mohavensis. The mitogenome has a nucleotide base composition of A (29.08%), T (26.91%), G (17.58%), and C (26.43%),...

The Owens Tui Chub Siphateles bicolor snyderi has become endangered by introgressive hybridization with the Lahontan Tui Chub S. bicolor obesa since the 1960s. Adequate conservation strategies require prior identification of pure populations, which is usually difficult because the diagnostic features presented in the formal subspecies description d...

Regression parameters for the length of several bony structures against fish body length, and for body length against body weight, were determined for Owens tui chub Siphateles bicolor snyderi, Lahontan tui chub Siphateles bicolor obesa, and hybrid swarm deriving from the two species. Two-hundred eleven individuals from 16 localities from the Owens...

The Owens Pupfish Cyprinodon radiosus represents many of the challenges of managing threatened or endangered species in fragmented refuge populations. All six extant populations of the endangered Owens Pupfish were examined to assess how management practices, including serial translocations and founder events, have influenced the genetic diversity...

The Mohave tui chub (Siphateles bicolor mohavensis) is the only fish native to the Mojave River, California. The fish were displaced by introduced arroyo chubs (Gila orcutti) throughout most of their range, starting in the 1930s. Two potentially relictual populations and two transplanted populations were genetically characterized using 12 microsate...
Article
Full-text available
Owens tui chubs (Siphateles bicolor snyderi [Miller]) have become extirpated throughout most of their range by introgression with introduced Lahontan tui chubs. The remaining non-introgressed Owens tui chub populations persist in a small number of fragmented habitats. These survivors are listed as “endangered” under both the state and federal endan...
Conference Paper
Full-text available
A small but active number of anglers oppose the restriction of bait from most of California's growing list of special management trout waters. The California Department of Fish and Game recruited some of these individuals into a volunteer project to examine aspects of bait fishing. The cooperative project compared the performance of baited circle h...
Conference Paper
Full-text available
Potassium permanganate is a common oxidizer used to detoxify fish toxicants applied to flowing waters. Mixing and delivery systems for permanganate application were refined during 5 chemical treatments to recover threatened populations of Lahontan cutthroat trout, Oncorhynchus clarki henshawi . Permanganate concentration is monitored using a portab...
