NOAA TECHNICAL REPORTS 

 National Marine Fisheries Service, Special Scientific Report— Fisheries Series 



The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to 

 understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for optimum use of the resources. NMFS is also charged with 

 the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign 

 fishing off United Stales coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing indu.stry through 

 marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of 

 the industry. 



The Special Scientific Report— Fisheries series was eaUblished in 1949. The series carries reports on scientific investigations that document long-term contmuing programs 

 of NMFS. or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery problems. The series is also used as a medium for the publica- 

 tion of bibliographies of a specialized scientific nature. 



NOAA Technical Reports NMFS SSHF are available free in limited numbers to governmental agencies, both Federal and SUte. They are also available in exchange for 

 other scientific and technical publications in the marine sciences. Individual copies may be obtained (unless otherwise noted) from D83, Technical Information Division.
