C. 20240 February 1970 AVAILABLE FISHERY BULLETINS OF THE U.S. FISH AND WILDLIFE SERVICE 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. Separates were issued as documents through volume 46; the last document was No. 1103. Be- ginning 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 number of the Bulletin. Available Bulletins are distributed free to libraries and to a limited number of universities and other scientific cooperators.
