EK80 Water Column Sonar Data Collected During IYS-Franklin-22

Description

Fisheries and Oceans Canada conducted an ecosystem-based trawl survey from February 19 to March 21, 2022 on the CCGS Sir John Franklin. This survey targeted Pacific Salmon in the eastern Gulf of Alaska and contributed to the International Year of the Salmon pan- Pacific survey coordinated by the North Pacific Anadromous Fish Commission. There were 31 species sampled in 456 kg of catch, with Pacific Salmon making up 29% of the catch by weight. Overall, the Northern Sea Nettle, Water Jellyfish, and Sockeye Salmon made up the largest biomass within the catch. There were 2478 individual lengths and 1763 individual weights recorded, including 5 Pacific Salmon species (Oncorhynchus spp.). Sockeye Salmon and Chum Salmon were the most abundant Pacific Salmon species, followed by Coho Salmon, Pink Salmon and Chinook Salmon. Stomachs were examined for prey items, with euphausiids, unidentified remains, squid, amphipods and lanternfishes being the most common prey species for salmon. Biological samples including scales, otoliths, muscles, fin clips, gill clips, plasma, liver, gonads, and eyeballs were collected for lab analyses at the Pacific Biological Station, Fisheries and Oceans Canada (Nanaimo, BC), the Alaska Fisheries Science Center, National Marine Fisheries Service (Juneau, AK), the Alaska Department of Fish and Game (Juneau, AK) and the University of British Columbia (Vancouver, BC). Acoustic data were recorded during transit between stations. Associated information on the physical oceanography, macronekton and zooplankton composition was collected from 35 stations for analysis at the Institute of Ocean Sciences, Fisheries and Oceans Canada (Sidney, BC) in collaboration with the University of Victoria (Victoria, BC). ARGO floats were deployed at 6 stations.
