NOAA TECHNICAL REPORTS 



National Marine Fisheries Service, Circulars 



The major responsibilities of the National Marine Fisheries Serv-ice (NMFS) are to monitor and assess the 

 abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quan- 

 tity 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, develop- 

 ment and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal 

 waters, and the development and enforcement of international fishery agreements and policies. NMFS also 

 assists the fishing industry through marketing .service and economic analysis programs, and mortgage insurance 

 and vessel construction subsidies. It collects, analyses, and publishes statistics on various pha.ses of the industry. 



The NOAA Technical Report NMFS CIRC series continues a series that has been in existence since 1941. The 

 Circulars are technical publications of general interest intended to aid conservation and management. Publica- 

 tions that review in considerable detail and at a high technical level certain broad areas of research appear in 

 this series. Technical papers originating in economics studies and from management investigations appear in 

 the Circular series.
