While other Bonneville cutthroat outside of Bear Lake, particularly larger ones, do eat fish, most Bonneville cutthroat rely on insects for their food source. When it comes to being the prey instead of the predator, Bonneville cutthroat have to watch out for birds such as kingfishers and herons, river otters, bigger fish and, of course, : Casey Rock.

Tiplying the total trout abundance estimate by the proportion of the catch composed of each species. At each site, we calculated the proportion of Yel-lowstone cutthroat trout that were 10–20, 20–30, 30–40, and cm total length and compared the proportions between periods to test for changes in Yellowstone cutthroat trout size structure.

Duringthe piscivorous lake trout pop-ulation consumed an estimated 15 metric tons of cutthroat trout ( fish) composing 14% of the vulnerable cutthroat trout production.

The only salmonid native to the South Platte and Arkansas River basins, the greenback cutthroat trout was threatened by habitat loss, unregulated fishing, and invasions by introduced nonnative. Similarly, the mean A of 76% for wild trout in this study (mostly Rainbow Trout and Cutthroat Trout) was much higher than the average of 47% reported by Meyer et.

An important Great Basin ecosystem, the Lower Truckee River once provided connectivity between the saline waters of Pyramid Lake and ultra-oligotrophic waters of Lake Tahoe which once yielded Lahontan cutthroat trout (LCT) greater than thirty pounds.
