FIGURE B.35 Trawl effort off California, 1994–1996. Important trawl grounds off California, for the most part, are found from Monterey north to the Oregon border, and there is relatively intense fishing between Santa Cruz and San Francisco and between Cape Mendocino and Crescent City. Two relatively heavily fished cells also are reported off Grover City and Ventura. State regulations prohibit trawl fishing on the continental shelf south of El Segundo to the Mexican border, although some trawling occurs on the offshore banks of Southern California. No trawling is allowed within state waters (3 nautical miles).
