NOAA TECHNICAL REPORTS

National Marine Fisheries Service, Circulars

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 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, analyzes, and
publishes statistics on various phases 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.
Publications 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.

NOAA Technical Reports NMFS CIRC 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 D83, Technical Information Division, Environmental Science
Information Center, NOAA. Washington, D.C. 20235. Recent Circulars are:
