OMB Control Number: 0535–0150. Summary of Collection: The primary function of the National Agricultural Statistics Service is to prepare and issue state and national estimates of crop and livestock production, disposition, and prices, as well as specialty agricultural and environmental statistics. Public Law 96–362 was passed to increase the overall effectiveness and productivity of federal aquaculture programs by improving coordination and communication among Federal agencies involved in those programs. Aquaculture is an alternative method to produce a high protein, low fat product demanded by the consumer. Aquiculture surveys provide information on trout and catfish inventory, acreage and sales as well as catfish processed. Need and Use of the Information: The survey results are useful in analyzing changing trends in the number of commercial operations and production levels by State. The information collected is used to demonstrate the growing importance of aquaculture to officials of Federal and State government agencies who manage and direct policy over programs in agriculture and natural resources. The type of information collected and reported provides extension educators and research scientists with data that indicates important areas that require special educational and/or research efforts, such as causes for loss of fish and pond inventories of fish of various sizes. The data gathered from the various reports provide information to establish contract levels for fishing programs and to evaluate prospective loans to growers and processors. Description of Respondents: Farms; Business or other for-profit. Number of Respondents: 2,275. Frequency of Responses: Reporting: Monthly; Semi-annually; Annually.
