5203 |a"Fisheries and Oceans Canada conducted an ecosystem-based trawl survey from September 30 to October 8, 2019 on the CFV Sea Crest. This study targeted juvenile Pacific Salmon off North East Vancouver Island. There were 21 species sampled in 716 kg of catch, with 26% Pacific Salmon caught by weight. Overall, Opalescent Inshore Squid (29%), Chum Salmon (14%), and juvenile Sablefish (13%) were the most abundant species by weight. Lengths and weights were recorded for 14 species, including all 5 Pacific Salmon species (Oncorhynchus spp.). Juvenile Chum Salmon and Pink Salmon were the most abundant Pacific Salmon species with large catches throughout the study area, except within Queen Charlotte Sound. Chum Salmon had the lowest percentage of empty stomach (4%), whereas juvenile Chinook Salmon had the highest percentage of empty stomachs (20%). Juvenile Coho Salmon, Pink Salmon, and Sockeye Salmon were primarily feeding on euphausiids and amphipods. Chinook salmon were primarily feeding on Pacific Herring, as well as amphipods. Biological samples for genetic stock composition and energy density are at the Pacific Biological Station, Fisheries and Oceans Canada (Nanaimo, BC). Associated information on the physical oceanography and zooplankton composition was collected from 36 stations and analysed at the Institute of Ocean Sciences, Fisheries and Oceans Canada (Sidney, BC)"--Abstract, page v.
