    • Abstract:
      The article discusses bear predation of salmon on the Kamchatka Peninsula in eastern Russia. The Kamchatka brown bear, a subspecies of Ursus arctos, depends on salmon for adequate subsistence throughout hibernation. After hibernation, salmon spawning provides newborn cubs the opportunity to observe adult bears' fishing methods. This observation is integral to the development and survival of the cubs. Even so, approximately one-half of all Kamchatka bear cubs perish in their first year of life. The shortage of salmon is examined, with illegal fishing by humans being named as a major factor.
