The 20-fathom boundary line is defined by connecting a series of latitude and longitude coordinates, which generally approximate the depth contour. The 20-fathom boundary line is defined along the mainland coast, as well as separate and individually around the Channel Islands off California. The boundary line may be used to prohibit or restrict certain groundfish fishing activities in the commercial and/or recreational fishery between itself and another defined boundary. Regulations may vary by geographic area and by fishery. Please check current regulations for the area and fishery in which you intend to participate to determine applicability of the 20-fathom boundary line. See Twenty Fathom Groundfish Boundary Points - R7 - CDFW [ds3161] (https://apps.wildlife.ca.gov/bios6/?al=3161) for the specific coordinates.
This feature depicts the 20-fathom boundary line that can be used in California groundfish regulations. The 20-fathom boundary line is a connection of a series of GPS coordinates published in California regulations (California Code of Regulations Title 14, Section 35.00) that are intended to approximate underwater depth contours. This boundary, as well as the federal Rockfish Conservation Areas, are used in recreational and commercial groundfish regulations to avoid interactions with certain groundfish species of concern. For both the recreational and commercial fisheries, boundary lines may change during the year, between seasons and management area.
Attributes
area_name: Identifying name for a particular line at a particular depth contour, primarily distinguishes between coastwide lines and lines around islands.
region: The groundfish management area that the section of the line is in.
