Full Title

Authors Summary
The bycatch risk assessment toolkit (ByRA) is being used in Chile in a landmark collaboration between local and international marine mammal scientists and Chilean fisheries agency scientists and managers. As part of a larger project to assess the risk of marine mammal bycatch in Chilean fisheries, this report focuses on two of the major artisanal fisheries along the northern and central Chilean coast. The artisanal swordfish gillnet fishery, and the northern anchovy purse seine fishery. The species most at risk and at the highest consequence of bycatch to local populations were the dusky dolphin and Burmeister’s porpoises in both fisheries, and the fin whale in the swordfish gillnet fishery. The ByRA results will provide Chilean fisheries agencies with information on areas and seasons of bycatch risk for ongoing monitoring, as well as the levels of risk for various fishing gear at those times and locations, which can support precautionary actions, policies, and inform carefully designed research and management.

Abstract
The bycatch risk assessment toolkit (ByRA) is being used in Chile in a landmark collaboration between local and international marine mammal scientists and Chilean fisheries agency scientists and managers.

The artisanal swordfish gillnet fishery, and the northern anchovy purse seine fishery. The species most at risk and at the highest consequence of bycatch to local populations were the dusky dolphin and Burmeister’s porpoises in both fisheries, and the fin whale in the swordfish gillnet fishery. The ByRA results will provide Chilean fisheries agencies with information on areas and seasons of bycatch risk for ongoing monitoring, as well as the levels of risk for various fishing gear at those times and locations, which can support precautionary actions, policies, and inform carefully designed research and management.
