Abstract
The spawning biomass of Pacific herring, Clupea harengus pallasi, in San Francisco Bay and Tomales Bay was estimated to be 59,000 tons and 11,200 tons, respectively during the 1982-83 season. This represents a 40% decline in San Francisco Bay and a 50% increase in Tomales Bay populations. Unusually high ocean temperatures and record rainfall in California are believed to have affected the distribution and/or survival of herring and caused changes in spawning habits. (26pp.)
