Abstract

During the period October 1 - December 31, 1974, a total of six permanent subtidal stations and ten random intertidal stations were surveyed. Red tides and rough seas limited both the commerical abalone and sea urchin fishery activities. Most activity was concentrated between Diablo Cove and Pecho Rock. Divers, however, did work urchin beds as far north as Lion Rock. Sea otter counts have remained relatively stable with almost all individuals being observed north of Lion Rock. Fourteen random fishing stations were completed. Low catch rates reflected fishing success in areas with a heavy brown algae surface canopy. (12pp.)
