摘要：

Three forms of the Arctic charr were found to occur in the fresh waters of the region of Hornsund (S Spitsbergen): anadromous, stationary fluviatile, and landlocked lake form. The stationary zoobenthivorous populations from Lake Myrktjorn and the Revelva River are morphologically the most similar. The piscivorous forms are bigger in size and have more massive Jaw apparatus. The differences between piscivorous, anadromous and landlocked forms pertain mainly to body depth which may be associated with more efficient feeding by anadromous forms of deeper bodies.
