Injury Rates of Red King Crab, Paralithodes camtschaticus, Passing Under Bottom-trawl Footropes
The rate of injuries sustained by red king crab, Paralithodes camtschaticus, during passage under several types of bottom trawl footropes was examined using a modified bottom trawl in Bristol Bay, Alaska. Crabs were recaptured and examined for injuries after passing under each of three trawl footropes representing those commonly used in the bottom trawl fisheries of the eastern Bering Sea. Using the injury rate from tows with a floated footrope which minimized crab contact to account for handling injuries, injury rates of 5, 7, and 10% were estimated for crabs passing under the three commercial trawl footropes.
