History of the San Francisco Bay shrimp fishery

The historic shrimp fishing village at China Camp, in San Rafael, California

Shrimp fishing was commercially important on San Francisco Bay from the 1870s to the 1930s. The fishery was dominated by Chinese immigrants and Chinese-American fishermen using Chinese junks built in the United States, and traditional Chinese nets and fishing techniques. Millions of pounds of shrimp were caught each year at the height of the market.

Italian fishermen began catching shrimp in San Francisco Bay around 1869, followed by Chinese fishermen in 1871, using traditional bag nets imported from China. Soon, immigrant Chinese fishermen from Guangdong dominated shrimp fishing in Northern California. The Chinese also fished for shrimp in nearby Tomales Bay, but those fisheries were abandoned in the 1890s. Junks were built at several places along the West Coast of the United States by Chinese shipwrights using traditional techniques and local lumber.

By the end of the 19th century, dozens of traditional Chinese shrimp fishing junks built in California were operating on the bay. As many as nine to ten million pounds of shrimp were harvested from the bay annually before restrictions on the fishery were imposed.

Although a small quantity of shrimp were sold locally, most were boiled and dried, resulting in a shelf-stable product that was exported to China and Hawaii. Drying resulted in two products: one third by weight the higher-grade product, called dried shrimp meat, which was used for human consumption, and two thirds the lower-grade product, called shrimp meal, which was used for fish food and plant fertilizer.

Legal and regulatory restrictions

Political opposition to the fishery began in San Francisco in 1885, based on the assumption that bycatch in the Chinese nets was killing large numbers of desirable young fish, especially salmon and striped bass. The opposition was exacerbated by the prevalent anti-Chinese sentiment in California in the late 19th century. Studies showed that the concerns were greatly exaggerated, and that the fishermen ate or gave away the edible fish. A 1932 report concluded that "the average striped bass is too spry to be taken in any such rig." Restrictive regulations were implemented, beginning in 1901 with an annual four-month closure of the fishery during the height of the season, a ban on the export of dried shrimp in 1905, followed by a ban on Chinese nets in 1911, forcing a switch to beam trawl nets, which required motorized boats. Arrests of Chinese fishing crews were common in the first decade of the 20th century. The ban on exports was lifted in 1919, leading to a tripling in production in the 1920s.

California state fishery records show that in 1930, the catch was 2,687,831 pounds of shrimp from the bay, 35 boats were operating, and 72 men were employed. There were 12 shrimp fishing camps at Hunter's Point in San Francisco, and two in Marin County, including China Camp. Only a handful of traditional sail powered junks remained in service, and most of the boats were converted motorized junks or Western style fishing boats.

The fishery went into a steep decline in 1936, due to a collapse in the export market due to the ongoing effects of the Great Depression and the intensification of war and revolution in China. After World War II, the fishery was limited to a much lower volume catch for local sale as fishing bait. Third generation Chinese-American shrimp fisherman Frank Quan has continued small volume shrimp fishing into the 21st century, and still lives at China Camp. He had his 90th birthday in 2015.
