Lahontan cutthroat trout, Oncorhynchus clarki henshawi, are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. using rainbow trout and fathead minnows as surrogate species for several endangered fishes. This dataset is a record of fish distribution and activity for LAHONTAN CUTTHROAT TROUT contained in the StreamNet database. of cutthroat trout. Lahontan cutthroat trout are the largest inland cutthroat trout in the world and the only trout native to Lake Tahoe. Lahontan cutthroat trout (Oncorhynchus clarki henshawi) is endemic to the Lahontan Basin of northeastern California, northern Nevada, and southern Oregon. Among those affected, the 14 subspecies of cutthroat trout found across western North America have been subject to two extinctions and five listings as Threatened as per the Endangered Species Act. Use Constraints: Data are collected at the 1:100,000 scale and only on streams that are included in the PNW reach LLID-based routing system. Distribution and Habitat: Lahontan cutthroat trout, like other trout species, are found in a wide variety of cold-water habitats including large terminal alkaline lakes (e.g., Pyramid and Walker lakes); alpine lakes (e.g., Lake Tahoe and Independence Lake); slow meandering rivers (e.g., Humboldt River); mountain rivers (e.g., Carson, Truckee, Walker, and Marys Rivers); and small headwater tributary streams (e.g., Donner … Coldwater static acute toxicity tests were conducted with rainbow trout and three listed species of salmonids - Apache trout (Oncorhynchus apache), Lahontan cutthroat trout (Oncorhynchus clarki henshawi), and greenback cutthroat trout (Oncorhynchus clarki The largest cutthroat trout subspecies is the Lahontan cutthroat trout (O. c. henshawi). These bucktails feature a few custom colors such as midnight galaxy and cosmic candy. The Lahontan Cutthroat Trout (Oncorhynchus clarki henshawi) is native to the Lahontan basin of northern Nevada, northeastern California, and southeastern Oregon. It is one of the 14 recognized subspecies of cutthroat. ����q��`2Ә�B���RT5h��M��o� Surrogate species used in toxicity assessments must be carefully selected in order to be protective of listed species. In ideal environments, the Lahontan cutthroat trout attains typical weights of 0.25 to 8 lb (0.11 to 3.63 kg). The objectives of this study were to determine if landscape topography influences trout distribution, and if water temperatures control this response. Distribution:Lahontan cutthroat trout are native to the greater Lahontan basin in eastern California, southern Oregon, and northern Nevada (Trotter 2008, Figure 1). The habitat of the Lahontan cutthroat trout has been reduced by over 90% throughout its native range by massive habitat alteration, water diversions, and overfishing. Methods Lahontan cutthroat trout are endemic to the La- hontan basin, located in the northwest region of the Great Basin of northern Nevada, northeastern California, and southeastern Oregon (Behnke 1992). ��o�&�i�#j��Lh� ,���^Y�h� �������9�a#��P�L�%��)�BL�T�B�R����R m��K8*�$�u�V��H�|ĸ� �]ru���4즕m���OD!Km��&��(]
