5203 |a"Fisheries and Oceans Canada's mandated ecosystem based approach to fisheries management requires a comprehensive understanding of factors that affect species' distribution, abundance, and interdependencies. The Integrated Pelagic Ecosystem Survey (IPES) is the only broadscale survey in the Pacific Region that collects this information for the pelagic ecosystem. The goal of the IPES is to understand factors affecting the distribution, abundance, and food web linkages of pelagic fish species (e.g., Pacific Herring, juvenile Pacific Salmon). The IPES is an annual, random stratified survey on Vancouver Island's continental shelf, 2017-present, with comprehensive biological, stomach content, and physical- and biological-oceanographic sampling. IPES data are required for ecosystem monitoring and modelling, support for SARA-listed species, DFO's State of the Pacific Ocean reporting, and the State of the Salmon program. In 2023, Pacific Herring, Aequeorea, and adult Pink Salmon dominated catch weights. In 2023, biomass estimates of juvenile Coho, Chinook, Sockeye, and Pink Salmon were the highest since 2017. The most common prey in fish diets were Euphausiids, true crabs, and teleosts (primarily Pacific Herring). The IPES supports research into 1) linkages between oceanographic conditions and fish abundance and distribution; 2) Pacific Salmon ocean ecology; 3) forecasted adult fish returns, and 4) food-web dynamics"--Abstract, page vi.
