It was not the average “big bang” squid run off La Jolla last fall, as scientists sometimes call it when the normally large spawning groups turn up in extra large numbers. And while breeding typically lasts only a few days, this run lasted three weeks.
Squid runs don't happen every year. One likely reason for the surge was the shift from El Nino to La Nina weather patterns that brought cooler, nutrient-rich waters to the West Coast.
All of which made 2024 a boom year for California squid, already the most valuable squid fishery in the U.S. Fishermen landed more than 126 million pounds of squid, valued at over 67 million dollars, making it the top fishery in both volume and value, according to the California Department of Fish and Wildlife.
San Diego supports a major part of California's commercial market, mainly from April to October. Most fishing takes place at night using 60-foot size purse seine boats and specialized lighting systems to attract and catch squid, often on spawning grounds near shore.

Market squid, also known as opalescent squids for their mutable, iridescent white and purple colors, are small invertebrates, around 12 inches long, related to snails. Divers describe a ghostly adventure among moving white walls during spawning events.
In San Diego, the migratory species — found from Baja to Alaska — occurs around La Jolla Shores, the La Jolla Submarine Canyon, and an area off the main wall just north of V Point (Point Loma). The foraging creatures are a food source for marine animals such as sharks, dolphins and sea lions.
Fishermen target spawning squid because they die soon after they reproduce; they live only six to nine months. Scientists say that even without fishing, the entire population replaces itself annually, making the live fast-die young molluscs resilient to a high amount of fishing pressure.
Recreational fishers use squid as live or dead bait, while much of the harvest gets exported to China and Japan for processing. It may then be re-exported back to the U.S., in a long chain of travel and emissions. But officials say the fishery itself is managed in a way that supports a healthy population, which began with the adoption of the Market Squid Fishery Management Plan in 2004. To reduce overfishing, there are weekend fishery closures and regulations regarding the lights used to attract squid.
Still, there are no reliable estimates of the population size, and the overfished and overfishing status are unknown.
To ensure long-term conservation, environmental groups are seeking changes to the plan, which is scheduled for potential adoption by the the California Fish and Game Commission in August. For one, requiring updated net parts that reduce contact with the ocean floor, to avoid disturbing egg beds.
It will be the first amendment to a California fishery management plan ever considered.
