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 
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 
the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillai 
fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing ini 
marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on v 
the industry. 
The Special Scientific Report—Fisheries series was established in 1949. The series carries reports on scientific investigations that document long-term continuing pr 2 
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 
tion of bibliographies of a specialized scientific nature.
