the threat for a niimber of years j but the emergency had not been 

 sufficiently great to attract support for research on the problem. 

 Most of the 19h8 appropriation was consumed in the construction 

 of the experimental weir in the Ocqueoe River and the 19 U9 allot- 

 ment amounted to barely ^^^OOOo Consequently^ it was not possible 

 in either year to carry out more than perfunctory research on the 

 lamprey-=appraisal3 of damage to the fishing industry j, short-term 

 surveys of streams to locate spawning runsj^^-o Serious experi- 

 mentation on control methods was out of the question,, Alfred 

 Perliraitter, who had been transferred from North Atlantic Fishery 

 Investigations in 19U8 to head the sea lamprey studies, resigned 

 in 19i+9. 



The substantial allotment for fiscal year 19^0 (which, be- 

 cause of delays in appropriatioRj, did not become available until 

 November 19lt9) made it possible for the first time to organize a 

 comprehensive research program bassd entirely on Service funds. 

 In consideration of the burden that the establishment and adminis- 

 tration of a greatly expanded program would impose. Van Oosten^ 

 at his request, was relieved of administrative duties to give full 

 time to the completion of his numerous researches in progress and 

 James ¥» Moffett was transferred from Central Valley Investigations 

 to become the new Chief (January 1950), 



In the development of the new Great Lakes program the following 

 full-time biologists were added to the staffs Vernon C, Applegate 

 {vfho had conducted pioneer researches on the sea lamprey under the 

 sponsorship of the Michigan Department of Conservation) 5 Paul H. 

 Escluneyeri Leo F. Erkkilaj Leonard S. Joerisj Louella E, Cable? 

 Bernard R. Smithj Albert E, Hallj, Jro| Howard A, Loebj Willis S. Gliddenj 

 Alberton Lo McLaini Phillip S. Parker. George F. Lunger joined the 

 staff as statistician. 



Stanford H. Smith, who had joined the Great Lakes staff in I9I4.9 

 a part-time fishery biologist, continued in that capacity. Other part- 

 time biologists were Robert E. Lennon, Philip J. Sawyer, and Roland L. 

 Wigley, 



Headquarters for the expanded Great Lakes Fishery Investigations 

 have ccntirmed to be in Ann Arbor, Micho Field laboratories have 

 been established at Hammond Bay (near Rogers City, Mich.) on Lake 

 Huron, at Marquette, Mich., on Lake Superior, and Sturgeon Bay, Wis., 

 on Lake Michigan. A research vessel, the Cisco , specially designed and 

 constructed for investigations on the Great Lakes has been considered 

 an independent station. The major activity of the enlarged Investiga- 

 tions h^as been research on the sea lamprey, with special emphasis on 

 the development of control methods o The Hammond Bay Laboratory at 

 which approximately half of the entire scientific staff is located 

 is concerned exclusively with sea lamprey research. Much of the ac- 

 tivity at the other field stations and in the Ann Arbor office is 

 in direct collaboration with the Hammond Bay group or concerned with 

 problems relevant to the control of the sea lamprey or the study of 

 its effects on fish populations in the Great Lakes.
