Description:

The outcomes of this report should serve as a guide to improve the understanding of the potential for interactions between commercial and recreational fisheries and large whales along California, Oregon, and Washington, recognizing that there are still many challenges in understanding the risk of whale entanglements and identifying gear. Based on the 35 years of whale entanglement data analyzed in this review, future work is recommended in the following areas: 1) Improve reporting to NMFS: increasing public awareness and understanding of the need for early and accurate reporting, expanding geographic reporting party coverage, support large whale entanglement response network to gain better documentation (e.g., photo identification, gear identification, injuries) and quality of information collected from each entanglement report; 2) Improve understanding of the ecological drivers affecting the distribution of whales and their risks of interaction with U.S. West Coast gear, and develop tools to assist with predicting distributions based on those drivers; 3) Improve understanding of the dynamics of the West Coast fixed gear fisheries, and develop tools to assist with monitoring/predicting those distributions; 4) Enhance understanding of how behavior of whales and different gear configurations may interact to increase/decrease chances of entanglements occurring; 5) Continue gear research and development of innovative ideas in collaboration with fishermen to reduce the number and/or severity of future entanglements, specifically for the U.S. West Coast; and 6) Continue and expand fishery gear marking initiatives based on evaluations of whale entanglement report data and success/failure of current marking schemes to identify the origins of entanglements.
