Cutthroat Trout

For Cutthroat Trout, minimum length categories are sub-stock (0 mm), stock (200 mm), quality (350 mm), preferred (450 mm), memorable (600 mm), and trophy (750 mm). Figure 3.5-5 provides the PSD for Cutthroat Trout resulting in a value of 99 percent and shows that the population of Cutthroat Trout contain almost exclusively large fish. Cutthroat Trout are currently a species stocked in Seminoe Reservoir as part of the WGFD stocking program, although stocking numbers of Cutthroat Trout are significantly less than for Rainbow Trout and only occurred in three of the last twelve stocking years. Based on these stocking numbers and the relative size stocked by WGFD, it is expected that Cutthroat Trout would be equal to or greater than stock size unless some natural reproduction is occurring in the tributaries to or within Seminoe Reservoir.
