    • West Coast Groundfish Bottom Trawl Survey Data - 2020 West Coast Groundfish Bottom Trawl Survey and indices of abundance

    Metadata Updated: October 19, 2024

    The Fisheries Research Survey team proposes to conduct the West Coast Groundfish Bottom Trawl Survey from May to October 2019. The goal of the survey is to ensure the sustainability of marine fisheries with a focus on ending overfishing. The groundfish fishery supports management for 90+ commercially fished stocks off Washington, Oregon, and California and is the primary source of fishery-independent data necessary for stock assessments of managed groundfish species inhabiting trawlable habitat along the upper continental slope and shelf. The survey provides data on abundance, spatial distributions, sex, length, maturity, weight, and age structure of groundfish in trawlable habitats. The survey also collects key environmental data (temperature, depth, dissolved oxygen, turbidity, in vivo fluorescence, irradiance, wind speed, location) in association with each tow for use in ecosystem based fisheries management. This data set contains information on date, time, vessel, trawl identification (i.e. unique number), trawl performance, location, depth, area swept, trawl duration, temperature, species, haul weight, average individual weight, sex, length, length method, fish age and age structure.
