The Science
Taxonomic description
- Small schooling fish that can reach 46 cm (18 inches) in length, but typically is not longer than 22.9 cm (9 inches). [1]
- Typically has a dark blue to olive color on its back, which fades to a silver belly. There are no distinctive dark spots. [2]
Distribution
- Found in schools off the coasts of the Arctic, Western Pacific, and Eastern Pacific. Found throughout the coasts of California, but is more common in Northern California. [2]
Life history
- Lives 8 to 16 years, and reaches sexual maturity at about 3-4 years. [1]
- When reproducing, travels into inshore estuaries to breed. A female herring will turn to her side to deposit her eggs on the bottom or on kelp, while a male herring will release milt to fertilize the eggs. [2]
- In California, spawning occurs from November through April. Females can lay up to 20,000 eggs each year! [1,16]
Habitat
- Stays by the coast and does not migrate extensively, and some landlocked populations exist. [2]
- In the summer of its first year in life, a young herring will join schools in shallow bays, inlets, and channels near the surface. By the fall, the herring will stay in deep water for 2-3 years. It will travel back to inshore estuaries to breed. [2]
- When young, feeds on crustaceans and decapod and mollusk larvae, while adult herring feeds on large crustaceans and small fishes. [2]
- At all life stages, it is vulnerable to predation, variability in ocean temperature and salinity, and longer-term climate change effects. [11]
The Fishery
Seasonal availability
- Commercial fishing for Pacific herring in California occurs in San Francisco Bay, Tomales Bay, Crescent City Harbor, and Humboldt Bay. [4]
- The fishery season varies from year to year, but is typically open during winter months. [4]
Regulatory and managing authority
- Managed federally by the NOAA fisheries and, as established by the Magnuson-Stevens Act, the Pacific Fishery Management Council (PFMC) through the Coastal Pelagic Species Fishery Management Plan (CPSFMP) as an Ecosystem Component Species. [17]
- As established by the Marine Life Management Act, the California Fish and Game Commission (CFGC) regulates the fishery in state waters, and the California Department of Fish and Wildlife (CDFW) collects data and helps enforce FMP management rules for this fishery through the Pacifc Herring Fishery Management Plan. [4]
- The Pacifc Herring Steering Committee combines input from the industry and government entities to inform regulatory and management measures for this fishery. [4]
Gear type
- Fished in California using set gillnets, purse seines are used outside of California. [5]
- Herring eggs on kelp (known as HEOK) is harvested by hand. [5]
Status of the fishery
- Three types of Pacific herring fisheries: fisheries exist for whole fresh fish, sac roe, and roe on kelp. [5]
- Well-managed fishery, regulations adapt annually to changes in the herring population. [4,5]
- Currently, the California fishery is only allowed to take 5% of the estimated spawning biomass. [5]
Potential ecosystem impacts
- As it plays a significant role in the food web, declines in this fish's population from overfishing, pollution, or other environmental issues could potentially have rippling effects through the ecosystem. [5]
The Seafood
Edible portions
- Whole fish can be eaten, and bones can be consumed. [6]
- The eggs-known as roe-are also eaten. [7]
Description of meat
- The meat is flaky, mild-tasting, and oily. [6]
- The roe has a slight crunch and texture similar to caviar. [7]
Culinary uses
- Extremely versatile--can be smoked, baked, grilled, pan-fried, fried, pickled, salted, canned, dried, and more. [6,7,8]
- Herring is a favorite cuisine in many parts of the world and different regions have unique ways of preparing and eating them! [6,7,8]

Nutritional information
- This fish is rich in Vitamin B12, protein, and Omega-3 fatty acids. [10]
- A table of nutritional information for 100g of raw Pacific herring is on the right. [10]
Seasonal availability
- Most Pacific herring is exported, but availability should follow the fishing season. [5]
