Abstract

Permanent subtidal stations 6, 11 and 16 were surveyed. Appreciable increases in densities of one species of brown algae and five species of macroinvertebrates were noted at station 6. Winter surveys of random and permanent intertidal stations were completed. There was little or no change in black and red abalone, Haliotis cracherodii and H. rufescens, densities at the various random study areas. There was a noticeable increase in black abalone numbers at permanent station 2A located in North Diablo Cove. Three new permanent stations were established and counts of abalone completed. Approximately 100 sea otters, Enhydra lutris, have moved from the Point Buchon area to the area around Pecho Rock. We fished at 13 random stations in Diablo Cove and five stations in North Cove and North Control to determine the catch rate of common sport fishes. A good percentage of the 1975 bull kelp, Nereocystis luetkeana, population weathered the winter storms. We calculated an approximate 18% over-wintering survival rate. Daily observations of foam in Diablo Cove continued; large amounts of piled-up foam have been observed during low tides in the South Diablo intertidal during periods of northwesterly winds. On a recent reconnaissance dive in Intake Cove, fish numbers appeared to be on the increase and visibility appeared to be improving. (15pp.)
