LIST OF SPECIAL SCIENTIFIC REPORTS AND SPECIAL SCIENTIFIC 

 REPORT-FISHERIES OF THE U.S. FISH AND WILDLIFE SERVICE 



Special Scientific Reports (1940-49) are preliminary reports, 

 progress reports, and reports on investigations of restricted scope, intended 

 to aid management and utilization; and to help guide administrative or legisla- 

 tive action; issued in limited quantities for Federal, State, and cooperating 

 agencies. In 1949 the Special Scientific Report series was split into a fishery 

 series and a wildlife series, each with a new numerical sequence. The new 

 fishery series became the Special Scientific Report—Fisheries. (Reports 

 preceded by asterisks are out of print, but can be borrowed from some 

 public and college libraries. ) 



The Special Scientific Report-- Fisheries series has limited dis- 

 tribution and the reports are mailed direct to workers in the field of fishery 

 research and conservation and libraries. They are not sent to commercial 

 concerns for selling or lending.
