Only in the last decade has it been revived. OCEAN SHRIMP The infant ocean shrimp fishery of 1952 continued to grow this biennium. This relatively new commer- cial fishery was established as a result of exploratory and development work of the Marine Fisheries Branch. Production grew from 206,000 pounds in 1952 to 300,000 in 1954. In 1955 a total of 855,000 pounds of ocean shrimp \\ as taken in California waters, of which 501,000 pounds were landed in Crescent City. Bodega Ba\' shrimpers brought in 330,000 pounds but only 1,446 pounds were delivered in iMorro Bay. The shrimp yield through June 30, 1956, was 419,- 000 pounds, which represents a 22 percent increase over the amount landed in a similar period in 1955. The Crescent City shrimp fleet again led production w ith 308,000 pounds, whereas Bodega Bay fishermen caught 111,000 pounds. As a conservation measure the Morro Bay area \\as closed in 1956 to commercial shrimp fishing b\^ the Fish and Game Commission until such time as the shrimp stocks in that area reach a safe harvestable level. Alesh Experiments Shrimp net mesh testing experiments were con- ducted at sea aboard the N. B. Scofield in 1956. Fur- ther mesh size testing is scheduled in 1957 to obtain sufficient data to establish the optimum mesh size for commercial shrimp net regulations. Through the cooperation of commercial fishermen, man\' samples of the shrimp catch were taken in the Bodega Bay and Crescent City areas for size composi- tion anahsis. A study of the grow th rate and sexual maturity of the ocean shrimp has been completed under direction of the department. PISMO CLAMS From the annual Pismo clam censuses conducted in the winter
