Movement, Growth, and Production of Brown Trout in Sympatry with Brook Trout in a Southern Appalachian Stream

A 1,532-m reach of Laurel Fork, a second-order tributary of the Doe River, Tennessee, was divided into 37 study sections which were sampled every 3 months by electrofishing. Brown trout (Salmo trutta) and brook trout (Salvelinus fontinalis) were weighed, measured, given a unique mark, and returned to the section from which they were caught. Population estimates were made with the Jolly Seber technique. Movement, density, instantaneous growth rate, biomass, and production were calculated. A large portion of recaptured brown trout (87%) and brook trout (63%) had trimonthly movements <75 m...
