Nevada State Fish: Lahontan Cutthroat Trout
It might seem surprising that a trout could survive in fourteen of arid Nevada's seventeen counties. As you might guess, it's a hardy fish, occupying habitats ranging from mountain streams and alpine lakes to seasonal lowland streams and alkaline lakes where no other trout can survive.
Characteristics of Nevada Lahontan Cutthroat Trout
Lahontan cutthroat trout (Oncorhynchus clarki henshawi) is the largest subspecies of cutthroat trout, and the state fish of Nevada. It is one of three subspecies of cutthroat trout that are listed as federally threatened.
Although coloration is variable, this species is generally heavily marked with large, rounded black spots, more or less evenly distributed over the sides, head, and abdomen. Spawning fish generally develop bright red coloration on the underside of the mandible and on the opercle. In spawning males, coloration is generally more intense than in females.
Although the Lahontan cutthroat in Oregon were originally classified as Willow-Whitehorse cutthroat trout, genetic and taxonomic investigations led to its re-classification in 1991 (Williams 1991).
The Lahontan cutthroat trout is one subspecies of the wide-ranging cutthroat trout species (O. clarki) that includes at least 14 recognized forms in the western United States. Cutthroat trout have the most extensive range of any inland trout species of western North America, and occur in anadromous, non-anadromous, fluvial, and lacustrine populations (Behnke 1979). Many of the basins in which cutthroat trout occur contain remnants of much more extensive bodies of water which were present during the wetter period of the late Pleistocene epoch (Smith 1978).
