In fact, evidence from across the West suggests that even when fish populations are wiped out of small streams following catastrophic fires, they rebound when fish migrate from surrounding streams, and populations usually reach pre-fire levels within 2 years (Gresswell 1999; Rieman et al.

For example, in Heart Lake there were seven fish species in the lake prior to the introduction of lake trout (Varley and Gresswell 1988). Why are cutthroat trout uncommon in lake trout stomachs in Jackson Lake, Wyoming? Even non-anglers benefited from the cutthroat trout in the lake, and almost 350,000 visitors (10% of the park visitation in 1990 and 1991) visited Fishing Bridge and LeHardy Rapids to watch the thousands of cutthroat trout that moved through those areas on their annual spawning migration (Gresswell and Liss 1995). There was little concern for whether these interactions with native trout were harmful; the main goal was to provide fish for anglers. Fresh or frozen rainbow trout have the same nutritional value.

The brain mitochondria of rainbow trout show decreased levels of docosahexaenoic acid and a lower peroxidation index, suggesting a lower susceptibility of damage by oxidative stress and a different reaction to growth compared to heart mitochondria.

It is possible the cutthroat trout are less common in the stomach contents of lake trout caught since the cutthroat trout population severely declined, and researchers from Montana State University are currently analyzing samples collected in 2013 to evaluate current diet structure (Syslo, unpublished data).
