摘要

Removal of killer whales from Greater Puget Sound, State of Washington, waters in the 1960's and early 1970's had an unknown impact on the population(s) of killer whales. Information on killer whale behavior, movements, group composition, social dynamics and individual growth and development is needed to properly protect and conserve this species in Puget Sound and connecting waters, and to help understand what impact removal of killer whales may have had on the population. Presented here are data from a study of Puget Sound killer whales, 1976-1978; a study initiated to photographically identify individual killer whales. By the end of 1978, 122 encounters with killer whales had occurred with 783 hours of observation and 83.5 hours of acoustic recording.
