Diablo Canyon power plant site ecological study Quarterly Report no. 7; January 1 - March 31, 1975
During the period January 1 - March 31, 1975 we relocatedand remarked five permanent subtidal stations and surveyed 28 random and two permanent intertidal stations. We failed to find a single giant red sea urchin, Strongylocentrotus franciscanus, around station 16 during a dive in March. Abalone, Haliotis spp., numbers decreased at random intertidal stations in North Diablo Cove and the North Control Area.The commerical sea urchin fishery was inactive, while the commerical red abalone, H. rufescens, fishery continued to operate around Pecho Rock.Counts of sea otters south of Point Buchon increased significantly, 20 to 30 otters are now feeding just north of Pecho Rock.Eight random fishery stations in Diablo Cove, Lion Rock Cove and the North Control Area yielded a substantial increase in catch-per-unit-of-effort.
