Rockfish Recruitment and Ecosystem Assessment Survey, Catch Data

Latest version published by United States Geological Survey on Nov 15, 2019 United States Geological Survey

The Fisheries Ecology Division (FED, https://swfsc.noaa.gov/GroundfishAnalysis/) of the Southwest Fisheries Science Center (SWFSC) has conducted a midwater trawl survey off central California since 1983 with the primary goal of developing pre-recruit indices for young-of-the-year (YOY) rockfish (Sebastes spp.). The survey also samples numerous other components of the epipelagic micronekton, including other YOY groundfish (such as Pacific hake, Merluccius productus, and sanddab, Citharichthys spp ), coastal pelagic fishes (such as Pacific sardine, Sardinops sagax, and northern anchovy, Engraulis mordax) and other forage species. Additional details regarding the survey methods and results are described in Ralston et al. (2015) and Sakuma et al.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 2,562 records. 1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Event (core)
    2562
  • Occurrence 
    471986

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
