Abstract
The spawning biomass of Pacific herring, Clupea harengus pallasii was estimated for Tomales Bay and San Francisco Bay during the 1973-74 and 1974-75 spawning seasons. Estimates involve determining numbers of eggs spawned and converting this figure to tons of herring. Age composition of the catch indicates the populations of both bays are stable. The spawning biomass was estimated at 6,559 tons and 4,734 tons in Tomales Bay for the 1973-74 and 1974-75 seasons, respectively. Spawning biomass estimates for San Francisco Bay were 6,127 tons and 19,465 tons for the 1973-74 and 1974-75 seasons, respectively. (46pp.)
