Abstract
The spawning biomass of Pacific herring in San Francisco Bay and Tomales Bay was estimated to be 65,441 tons and 5,583 tons, respectively during the 1980-81 season. This is the highest estimate to date for San Francisco and continues a rising trend in abundance. The Tomales Bay population has fluctuated around an annual mean of 6,000 tons since 1973. (24pp.)
