State-Managed California Commercial Herring Fishery

California Commercial Herring Fisheries Information Opportunities for Public Involvement and Input

Due to an historic low 2008-2009 season spawning biomass estimate and concerns over the health of the Pacific herring population, the Fish and Game Commission adopted a zero quota for San Francisco Bay for the 2009-2010 season. This results in a zero quota for the herring roe, fresh fish market, and herring-eggs-on-kelp fisheries in San Francisco Bay for the 2009-2010 season.

The commercial herring fishery is one of the few fisheries in California that undergo annual population assessments and subsequent regulatory change. Like other short-lived coastal pelagic species, Pacific herring abundance fluctuates widely due to variable recruitment (the success of each year-class of new fish), making annual population assessments necessary for effective management. This allows the Department and the Commission to integrate new information into management of the fishery on a timely basis.

Pacific herring are found throughout the coastal zone from northern Baja California on the North American coast, around the rim of the North Pacific Basin to Korea on the Asian coast. In California, herring are found offshore during the spring and summer months foraging in the open ocean. The largest spawning aggregations in California occur in San Francisco and Tomales bays. Beginning as early as October and continuing as late as April, schools of adult herring migrate inshore to bays and estuaries to spawn. Schools first appear in the deep water channels of bays, where they can stay for up to two weeks as their gonads mature, they then move into shallow areas to spawn. Most spawning areas are characterized as having reduced salinity with calm and protected waters. Spawning-substrate such as marine vegetation or rocky intertidal areas are preferred but man-made structures such as pier pilings and riprap are also frequently used spawning substrates in San Francisco Bay.

Most herring fisheries occur during the spawning season. The roe herring gill net fisheries catch herring as they move into the shallows to spawn when the eggs have fully matured. The primary product from this fishery, kazunoko, is the sac roe (eggs) in the females which are processed and exported for sale to Japan. California's roe herring fisheries occur in the Crescent City Harbor area, Humboldt Bay, Tomales Bay, and San Francisco Bay.

The San Francisco Bay herring eggs-on-kelp fishery suspends giant kelp, Macrocystis pyrifera, from rafts for herring to spawn on in shallow water areas. The kelp is harvested near the Channel Islands and/or in Monterey Bay and then transported to San Francisco Bay. The product of this fishery is the egg-coated kelp blades that are processed and exported to Japan. This product, komochi or kazunoko kombu, is typically served as an appetizer during New Year's celebrations.

The only open ocean fishery for herring in California occurs during the non-spawning season in Monterey Bay. Landings from this fishery enter the aquarium food and bait markets. Fishing for fresh fish is also permitted during the non-spawning season in Tomales Bay and San Francisco Bay.

California Environmental Quality Act and Annual Regulatory Process

The Pacific herring commercial regulations are updated every year. In addition, potential environmental impacts of the fishery are addressed each year in an environmental document, in accordance with the California Environmental Quality Act (CEQA). Both the regulatory and CEQA processes provide the public with several opportunities each year to provide input to the Department and the Commission on the management of California's Pacific herring resource.

Pacific Herring Fishery Management Plan

The MLMA requires that Fishery Management Plans (FMPs) form the primary basis for managing the state's marine fisheries. An FMP is a planning document based on the best available scientific knowledge and other relevant information, that contains a comprehensive review of the fishery along with clear objectives and measures to ensure its sustainablitly. The Department is implementing the goals of the MLMA by beginning the preparation of a Pacific Herring FMP.
