摘要: Abstract Eight small pit lakes, located in the Pigeon River State Forest, were considered to be ecologically suited trout as determined by a physical, chemical, and biological survey of these lakes 1931 1932. Four found over-run with yellow perch, other four originally contained only forage fish. Trout (chiefly brook trout) stocked each lakes.
