Friends of the Berkshire National Fish Hatchery works cooperatively with the U.S. Fish and Wildlife Service to support their work to restore lake trout populations in the Lower Great Lakes by supplying multiple strains of lake trout eggs to other Federal hatcheries. These eggs are hatched and grown to seven inches at the Berkshire National Fish Hatchery and are then stocked in Lakes Ontario and Erie. With assistance from the Berkshire Hatchery Foundation, native brook trout are raised for stocking in local waterways to support recreational fishing, public youth fishing events and educational programs at the Hatchery, and at other locations throughout the Berkshires.
