Abstract
Movements of northern pike (Esox lucius) in Lac Ste. Anne, Alberta were monitored for 5 to 47 days using ultrasonic transmitters which were implanted in the fishesˈ stomachs. None of the nine fish studied established well-defined home ranges. The pike were usually found within 300 m of shore and in water less than 4 m deep. No major differences were found in the extent of movement or in habitat selection between summer and winter. Daily pike movements were from 0 to 4,000 m, but most daily movements were less than 1,000 m.
