Review of salmon bycatch in the Pacific Region 2022/23 groundfish trawl fishery and preliminary results of an enhanced monitoring program / Cory R. Lagasse, Kathryn A. Fraser, Rob Houtman, Erik Grundmann,...: Fs97-4/3273E-PDF
"The Pacific Region groundfish trawl fishery is one of the largest fisheries in British Columbia by catch volume and value, operating throughout the year with all fishing trips subject to at-sea electronic monitoring and independent validation of landings via a dockside monitoring program. An enhanced monitoring and sampling program for salmon bycatch was initiated for all Option A trawl licence holders on September 26, 2022 to improve the accuracy of estimates of salmon catch by species and collect coded wire tag (CWT) and stock composition information to assess potential impacts on Chinook salmon (Oncorhynchus tshawytscha) stocks of concern. This report summarizes estimates of Pacific salmon bycatch in the groundfish trawl fishery since 2008, with a focus on the 2022/23 fishery. Catch of Pacific salmon in the 2022/23 fishery was the highest recorded since 2008 with a total catch of 28,117 Pacific salmon, including 26,273 Chinook salmon. Most of this catch occurred during the enhanced monitoring period from September 26, 2022 to February 20, 2023, with 15,234 Chinook salmon sampled during this period for CWT analysis and estimation of stock composition. The enhanced monitoring program will continue to be implemented through the 2023/24 fishery with additional results described in future reports"--Abstract, page iv.
