Bret Ladago, left, a fisheries biologist with the Vermont Fish and Wildlife Department, stuns wild trout in Broad Brook on Sept. 26, 2017, to be weighed, measure and released. Others are retained to be tested for disease. With him are Cooper Brochu, middle, a season fisheries technician, and Chris Powers, a fish and habitat specialist, both with Vermont Fish and Wildlife. The department has used the 500-foot section of the brook in South Royalton, Vt., to monitor trout for 20 years. (Valley News - Jennifer Hauck) Copyright Valley News.
