Escape of Dungeness crabs (Cancer magister) from baited commercial crab pots in the Columbia River estuary was examined. During a 28‐day period (12 October‐10 November 1982), 185 male crabs were captured and tagged. Sixty percent of the crabs escaped, the majority within 2 days. Size, leg loss, and leg regeneration were not significant factors in escapement.
