Abstract

Since the inception of a sac-roe fishery for Pacific herring, Clupea pallasi, in 1973, the California Department of Fish and Game (Department) has annually assessed the status of the state's two largest spawning populations of herring in Tomales and San Francisco Bays. Each year the Department's Pacific Herring Research Project estimates spawning biomass, determines the age structure of the spawning population, examines growth and general condition, estimates the relative abundance of young-of-the-year herring, and monitors the biological aspects of the catch. This information, along with environmental factors, is considered and used to set the harvest quota for the following season's fishery. San Francisco Bay supports the largest spawning population of Pacific herring in California, as well as the largest commercial herring fishery. Spawning generally occurs from November through March, in the intertidal and shallow subtidal zones of the central and southern regions of the Bay. This report presents work conducted during the 1993-94 spawning season and continues the time series of information for the San Francisco Bay spawning population. (36pp.)
