Abstract

This dataset depicts the boundaries of the Trawl Rockfish Conservation Areas (RCA) off the West Coast of the United States.Trawl Rockfish Conservation Areas (RCA) are areas closed to commercial fishing for groundfish with trawl gear. Closures may vary seasonally. Boundaries are defined by 1) lines that connect a series of coordinates that approximate particular depth contours 2) specific lines of latitude. These boundaries are defined in Code of Federal Regulations. For Trawl RCA this has been defined as:North of 46° 16'N latitude and the the 100 fm line and 150 fm line. For information on the official legal definition refer to the Code of Federal Regulations:Table 1 (North) to Part 660, Subpart D, Title 50https://www.ecfr.gov/current/title-50/part-660/appendix-Table 1 (North) to Part 660, Subpart DTable 1 (North) to Part 660, Subpart D, Title 50The feature class naming convention reflects the date (YYYYMMDD) that the RCAs were published in the Federal Register (FR).

Purpose

This data delineates Trawl Rockfish Conservation Areas (RCA) off the West Coast of the United States. Trawl RCA are areas that are closed to commercial fishing.

Data Access & Downloads

  • ESRI File Geodatabase

    NOAA Fisheries GIS Portal

    This geodatabase contains spatial data for NOAA Fisheries West Coast Region (WCR) Groundfish Conservation Areas (GCA).

    GCA's are conservation areas created or modified and enforced to control catch of groundfish or protected species (50 CFR 660.11 “Conservation area(s)”.

    The following WCR groundfish conservation area types are included in this geodatabase:

    YRCA - Yelloweye Rockfish Conservation Areas

    GEA -Groundfish Exclusion Areas

    CCA - Cowcod Conservation Areas

    RCA - Rockfish Conservation Areas

Use Constraints:

This GIS feature class includes boundaries for the Trawl Rockfish Conservation Area (RCA). Because GIS projection and topology functions can change or generalize coordinates, this GIS file is considered to be an approximate representations and is NOT an OFFICIAL record for the exact regulated area boundaries. For information on the official legal definition refer to the Code of Federal Regulations:Table 1 (North) to Part 660, Subpart D, Title 50https://www.ecfr.gov/current/title-50/part-660/appendix-Table 1 (North) to Part 660, Subpart D

URL where the source data were originally accessed.

Source Contribution:

To define 100-fm and the 150fm contour lines, coordinates for the depth contours were obtained from NOAA Fisheries in CSV format. Coordinates were plotted and the Points-to-Line geoprocessing tool was used (ESRI ArcPro GIS software). These two depth contours define the east-west boundary of the Trawl RCA
