Rockfish Conservation Areas (RCAs) are closed areas for west coast groundfish fisheries and for some fisheries that may incidentally take groundfish as bycatch. The RCA boundary line is a connection of a series of GPS coordinates published in federal regulations (See 50 CFR 660.71-660.74) that are intended to approximate underwater depth contours. RCA boundaries are used in groundfish regulations to avoid interactions with certain groundfish species of concern and may change between seasons and Recreational Fishing Management Areas. The process of digitizing these boundary lines is as follows:30, 40, 50, 100, and 150fm waypoint .csv files at were downloaded from NOAA''s West Coast Groundfish Closed Areas website https://www.fisheries.noaa.gov/west-coast/sustainable-fisheries/west-coast-groundfish-closed-areas and imported into ArcGIS Pro.Each point feature was clipped to the borders of California state waters and merged together.“Fathom” was added as a field to each shapefile and populated with the corresponding depth in fathoms.Boundary lines for each shapefile (30, 40, 50, 100, and 150 fm) were created using the “Points to line” tool.

This dataset is for the archival purpose of demonstrating the extent of the Cowcod Conservation Areas. In 2001, access to the continental shelf in the Southern California Bight was restricted by the implementation of the Cowcod Conservation Areas (CCAs) that prohibit most bottom fishing. The closed area includes a 4,200 square mile area (Area 1, or Western CCA) off the Palos Verdes Peninsula extending southwards about 90 miles and westward another 50 miles. A smaller area, the "43-fathom spot" (Area 2, or Eastern CCA), which lies 40 miles offshore of San Diego and extends northward and offshore to cover 100 square miles, was also designated a part of the closure area. Starting in 2024, CCA restrictions no longer apply to non-trawl commercial and recreational vessels fishing for groundfish. Attributes Area: ID for each CCA. Name: Informal Description of each area.

This dataset depicts the eight Groundfish Exclusion Areas located in the Southern California Bight in the area formerly encompassed by the Cowcod Conservation Areas. The Groundfish Exclusion Areas restrict take and possession of groundfish, except for purposes of continuous transit. Fishing for non-groundfish stocks is permitted provided no groundfish are aboard. Located north of Santa Barbara Island, the Hidden Reef GEA measures 5.7 by 6.6 miles. The West of Santa Barbara Island GEA measures 12.6 by 7.9 miles. Located west of San Nicolas Island, the Potato Bank GEA measures 8.5 by 13.8 miles. To the south-west of San Nicolas Island, the 107/118 Bank GEA measures 9.1 by 6.8 miles. Located north/north-west of Tanner Bank, Cherry Bank GEA measures 13.9 by 3.9 miles, with the Seamount 109 GEA measuring 19.8 by 3.7 miles (on the southern end) located west of the bank. Roughly 25 miles west of Cortes Bank, the Northeast Bank GEA measures 6.3 by 10.1 miles. Roughly 49 miles west of San Diego, the 43-Fathom Spot GEA measures 8.0 by 11.2 miles.AttributesID: ID for each GEA.AreaName: Informal Description of each area.
