Abstract

Ovigerous Dungeness crabs were collected from the San Francisco and Eureka-Crescent City regions and maintained at the Department's Marine Culture Laboratory near Monterey. Hatching success, expressed as viable larvae released, was measured and compared by region. Larval counts were made from 15 Dungeness crabs, 5 from the San Francisco region, 7 from the Eureka-Crescent City area and 3 of unknown origin. Mean hatching success exceeded 80% in the San Francisco region, and averaged more than 90% in the Eureka-Crescent City area. However, a Student's t-Test showed this difference in hatching success was not significant. (16pp.)
