Abstract

The progress of the research program in the year 1975 is presented. In addition to a report of project studies, discussions of program development, research procedures, and cooperative research efforts are included. The crab critical stage project studies included distribution and relative abundance of larvae and juvenile crabs in the Gulf of the Farallones, San Pablo Bay and San Francisco Bay. Several fish species were identified as crab predators, genetic structure of Dungeness crab populations were investigated, and growth rates of juvenile crabs were determined. The crab environment project collected historical and recent data on parameters of oceanographic factors including temperatures, salinities, currents, upwelling, sea level, and river flows into the bays and ocean. Environmental toxicant levels in crabs are being determined for a wide spectrum of heavy metals, pesticides, PCB's, and petroleum hydrocarbons. The Marine Culture Laboratory developed techniques for small and large scale culture of crabs from eggs held under controlled conditions to aid in design of laboratory tests of the effects of environmental factors on crab survival.
