ECOLOGY:

The food habits of the Rainbow trout are very similar to the Bonneville Cutthroat trout's. One difference is that the Rainbow trout spends most of its time in slower moving water and pools then the Bonneville Cutthroat trout This is do to the fact that the Rainbow trout is a slower swimmer then the Cutthroat trout
The reproduction habits of the Rainbow trout are very close to the habits of the Bonneville Cutthroat trout. Unlike the Cutthroat trout's, the Rainbow's reproduction is triggered by the warmth of the water temperatures (from February to June). The amount of eggs that a Rainbow trout may lay is dependent upon her size. The larger the female trout, the greater number of eggs she will lay.

The Environmental factors that effect and influence the Rainbow trout is almost identical to the Bonneville Cutthroat's environmental factors.
The introduction of Rainbow trout has altered the ecology of City Creek and in turn affected the living conditions of the Bonneville Cutthroat trout. Competition for the same resources between the Bonneville cutthroat trout and the Rainbow trout have caused the native Bonneville Cutthroat trout's population to decrease. The introduction of the Rainbow trout has altered the ecology of City Creek Canyon by the creation of hybrids, which is replacing the purebred species.
