Fishery Bulletin web site: www.fisherybulletin.noaa.gov 
The Fishery Bulletin carries original research reports on investigations in fishery sci¬ 
ence, engineering, and economics. It began as the Bulletin of the United States Fish Commis¬ 
sion in 1881; it became the Bulletin of the Bureau of Fisheries in 1904 and the Fishery Bulle¬ 
tin of the Fish and Wildlife Service in 1941. Separates were issued as documents through vol¬ 
ume 46; the last document was no. 1103. Beginning with volume 47 in 1931 and continuing 
through volume 62 in 1963, each separate appeared as a numbered bulletin. A new system 
began in 1963 with volume 63 in which papers are bound together in a single issue. Beginning 
with volume 70, number 1, January 1972, Fishery Bulletin became a periodical, issued quarterly. In 
this form, it is available by subscription from the Superintendent of Documents, U.S. Government 
Printing Office, Washington, DC 20402. It is also available free in limited numbers to libraries, 
research institutions, state and federal agencies, and in exchange for other scientific publications.
