ABSTRACT 



The present article is a revision and expansion of my earlier paper: 

 25 years of Federal Fishery Research on the Great Lakes. Spec. Sci. Rep.: 

 Fish. No. 85, 1952. Two circumstances made a revision desirable at this 

 time. First, publications since 1952 have added greatly to the literature based 

 on Federal studies on the Great Lakes. Second, the Great Lakes Fishery 

 Commission, established by treaty with Canada, was organized in Ottowa in 

 April 1956 and held its first annual meeting in Ann Arbor in November 1956. 

 The entry of the Commission on the scene marKs the start of an era of further 

 expansion and heightens interest in past activities.
