    Observation of Fish Behavior in Trawls: Finding Ways to Reduce Bycatch
  • Personal Author:
  • Description:
    Bycatch, defined as unintended fish mortalities resulting from fishing operations, significantly impacts several important fisheries in the North Pacific Ocean. Bycatch includes the discard of undersized or unmarketable fishes and of species that are prohibited to a fishery and is a growing concern of management agencies, the fishing industry, and the general public. With the goal of mitigating bycatch problems, the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC) has conducted research to aid development of fishing gear technology capable of both effective fishing and bycatch reduction. In recent years, research conducted by the Division in cooperation with industry and other research agencies has focused on the use of under water video to study fish behavior in and around operating bottom trawls. In situ observation of fish behavior has provided new data on both how and why a modification succeeds or fails, making it a powerful tool for developing and testing fishing gear.
