Fishery Bulletins are technical reports on scientific investigations of 

 fishery biology. The Bulletin of the United States Fish Commission was 

 begun 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. Sepa- 

 rates were issued as documents through volume 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 of the bulletin instead of being issued individually. 



Bulletins are distributed free to libraries, research institutions, State 

 agencies, and scientists. Some Bulletins are for sale by the Superintendent 

 of Documents, U.S. Government Printing Office, Washington, D.C. 20402.
