MONTPELIER, Vt. — The Vermont Department of Fish and Wildlife has been recognized for a study of wild brook trout populations that found the fish populations are secure in the state.

In a decade-long study, fisheries program manager Rich Kirn and his colleagues repeated a study done in the 1950s to determine how wild brook trout populations in Vermont fared over the decades.

Biologists sampled brook trout populations from streams across the state. They found that compared with the 1950s, brook trout are more abundant and the impact of nonnative trout been negligible.

The department says it received the 2017 Sport Fish Restoration Outstanding Project Award from the American Fisheries Society for the study.
