Ecosystem-based juvenile Pacific salmon (Oncorhynchus spp.) trawl survey off north and west coast Vancouver Island, British Columbia, October 8-23, 2022 / by Amy M. Tabata, Kelsey L. Flynn, Tyler B. Zubkowski,...: Fs97-13/1384E-PDF
"Fisheries and Oceans Canada conducted an ecosystem-based trawl survey from October 8-23, 2022 on the CFV Nordic Pearl. This study targeted juvenile Pacific Salmon off the North and West Coast of Vancouver Island. There were 35 species sampled in 3,065 kg of catch, with 9.5% juvenile Pacific Salmon caught by weight (291 kg). Jack Mackerel (Trachurus symmetricus), the genus Aequorea, Lions Mane jellyfish (Cyanea capillata) and adult Chum Salmon (Oncorhynchus keta) were the most abundant catch by weight. There were 4,088 individual lengths and 2,961 individual weights recorded, including all 5 Pacific Salmon (Oncorhynchus) species. Juvenile Pink Salmon were the most abundant juvenile Pacific Salmon species, with catches throughout the study area, followed by juvenile Chinook Salmon, Coho Salmon, Chum Salmon, and Sockeye Salmon. Juvenile Sockeye Salmon had the highest percentage of empty stomachs (14%). Common prey species for juvenile salmon included Pacific Herring, crabs, amphipods and euphausiids. Biological samples for genetic stock composition, otoliths, energy density, gills, and coded wire tags are at the Pacific Biological Station, Fisheries and Oceans Canada (Nanaimo, BC). Associated information on the physical oceanography (65 stations) and zooplankton composition (37 stations) was collected and will be analysed at the Institute of Ocean Sciences, Fisheries and Oceans Canada (Sidney, BC)"--Abstract, page v.
