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 resom-ces, 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, 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 as- 

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

 and vessel construction sub^dies; It collects, analyzes, and publishes statistics on various phases of the industry. 



The Special Scientific Report — Fisheries series was established in 1949. The series carries reports on scien- 

 tific investigations that document long-term continuing 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 publication of bibliographies of a specialized scientific nature. 



NOAA Technical Reports NMFS SSRF are available free in limited numbers to governmental agencies, both 

 Federal and State. 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 NOAA Publications Section,
