Food habits of sympatric and allopatric populations of adult brook trout (Salvelinus !ontinalis) and rainbow trout (Oncorhynchus mykiss) from 4 streams in the Great Smoky Mountains National Park were compared to determine if competition for food resources might explain the apparent exclusion of the former by the latter in Southern Appalachian streams. When diets of brook trout in sympatry with rainbow trout were compared with diets of brook trout in allopatry, there was little significant change in prey composition. Based on this information, exploitation competition for food resources...

A stocked rainbow trout (Salmo gairdneri) fishery in newly impounded Tellico Reservoir, Tennessee, was evaluated through creel surveys. In 1980, the first year of impoundment, trout made up 41.1% by weight of all fish harvested declining to a mean of 9.8% over the next 4 years. Estimated annual effort for trout averaged 53,000 hours. Rainbow trout catch rate averaged 0.067 fish per hour, and the harvest return of stocked rainbow trout averaged around 69% by weight over the 5-year period. Average catch per hour was lower than observed from other southeastern, 2-story trout fisheries....
