Robert Humston, a biology professor from Virgina’s Washington and Lee University, has been studying the
impact of stocked trout in reservoirs on the Commonwealth’s native
brook trout. His findings so far are fascinating: it turns out that the stocked trout may actually help the wild trout survive longer.

“Introducing this separate population of hatchery
trout with a different genetic signature is adding more variation. That
diversity increases the likelihood that a population can adapt to
changes,” he said. “At the same time, the hatchery trout haven’t
impacted the native species yet. And if we haven’t diluted any local
adaptation by the native trout they may be better able to persist in
the long term.”
