Pike; Fish culture; Lakes--Management


Methods for rearing, harvesting, and management use of pike (Esox lucius L) in Minnesota are described, especially as related to multiple use of shallow water areas. Principal emphasis is placed on the method of removing fingerling and yearling pike in winter from shallow lakes. Such lakes often raise wild rice and also are utilized by waterfowl. The pike, spawned naturally in these lakes, are harvested by pumping aerated water through fish traps when oxygen levels in the lake become low. Pumping is most effective when oxygen levels in the lake fall below 2 parts per million but is higher in the trap area.
