Summary

Description

Alaska’s Bering Sea is home to some of the world’s most productive groundfish and crab stocks and the fisheries that depend on them. Their spatial overlap creates problems when bottom trawls affect crabs in their paths, either through capture and discard or damage to crabs that remain on the seafloor. We worked with Bering Sea bottom trawlers to develop and test changes to trawl footropes to minimize crab mortality, by reducing damage to crabs that are not caught, and maintaining low crab capture rates.

Abstract:

Alaska’s Bering Sea is home to some of the world’s most productive groundfish and crab stocks and the fisheries that depend on them. Their spatial overlap creates problems when bottom trawls affect crabs in their paths, either through capture and discard or damage to crabs that remain on the seafloor. We worked with Bering Sea bottom trawlers to develop and test changes to trawl footropes to minimize crab mortality, by reducing damage to crabs that are not caught, and maintaining low crab capture rates.
