Area B-2 (Bodega Bay) was closed in July, 1957, when its quota of 400,000 pounds was reached. This area's early closure prompted the fleet to work in Area B-1 (Fort Bragg)—the first time commercial interests had at- tempted shrimping in this ai-ea. Its quota of 200,000 pounds was then reached by late September. OYSTERS California oyster production skyrocketed during 1956-57 and continued to hold strong in 1958. Oyster culture on allotted state lands and priv^ate beds yielded over 11 million pounds of Pacific oysters. Oyster allot- ments comprising 3,290 acres have been issued by the commission since 1955. There are now 12,700 acres designated shellfish culture areas. A Highly Developed Fishery 0\ster culture represents one of the most highly developed marine fisheries. California oystering may be called "aquaculture," paralleling agriculture in that seed is planted, a growing crop is cultivated, protected from pests, and fattened for harvesting. Aquaculture of oysters is dependent upon a successful spawning resulting in an abundance of free swimming larvae. Then actual culturing can begin. Unfortunately, California waters do not become warm enough for the length of time required for the development of Pacific oyster larvae. Therefore, seed production, the first step in oyster culture, is accom- plished in Japan where the Pacific oyster is native. Strings of oyster shells are put in Japanese bays and larvae attach themselves to surfaces of the shells at termination of their free swimming stage. These young oysters on shells are imported as "seed"
