California ranks among the leading states in the value of its fish catch. Among the most important commercial fish caught in Californian waters are species of tuna, salmon, halibut, mackerel, and anchovy. Shellfish taken in coastal waters include crab, shrimp, and abalone.
California usually ranks third among the states, after Oregon and Washington, in output of timber and lumber. Lumbering is the chief economic activity in the Sierra Nevada and in northwestern California. Redwood and Douglas fir are the most important commercial species in the northwest. Ponderosa or yellow pine is the principal commercial species in the Sierra Nevada. About two-fifths of the forestland is classified as commercial forest; more than half of the commercial forest is managed by the United States Forest Service.
California also ranks among the leading states in the value of its annual mineral output. Crude oil and natural gas account for the most valuable portion of California’s mineral production. However, oil production in the state began to decline in 1995, and a decade later California ranked fourth in the nation in the production of oil, behind Louisiana, Texas, and Alaska. California produces much less oil than it consumes.
California leads all other states in the production of sand and gravel for construction, Portland cement, diatomite, and sodium sulfate. In addition, much of the world’s supply of boron minerals comes from Searles Lake and other areas in California’s Mojave Desert. The state is also a leading producer among the states of feldspar, soda ash, titanium, and magnesium compounds. Gold is the chief metal mined in the state; silver is the only other metal, and only a small amount of silver is produced, as a byproduct of gold extraction.
