Fishery Bulletin web site: www.fisherybulletin.noaa.gov 
The Fishery Bulletin carries original research reports and technical notes on investigations in 
fishery science, engineering, and economics. It began as the Bulletin of the United States Fish 
Commission in 1881; it became the Bulletin of the Bureau of Fisheries in 1904 and the Fishery 
Bulletin of the Fish and Wildlife Service in 1941. Separates were issued as documents through 
volume 46; the last document was No. 1103. Beginning with volume 47 om 1931 and continu- 
ing 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 of the bul- 
letin. Beginning with Volume 70, number 1, January 1972, the Fishery Bulletin became a peri- 
odical, issued quarterly. In this form, it is available by subscription from the Superindentent 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 publicarions.
