Biological Survey — Genesee River 11 



list of si)ecies may include the following" : the small-mouthed bass 

 and suckers now in the river ; the pike-perch whose adaptability 

 to various conditions in the Genesee system has been well estab- 

 lished ; the yellow perch for game and as a food resource for other 

 fish; and possibly the lake trout and an inland lake cisco (a plank- 

 ton feeder) as another food resource. 



The Caneadea project is of lesser importance as a new lake 

 since operating- conditions are likely to introduce to a greater 

 extent the factor of variability in water level, and the possibility 

 of the basin becoming dry. Tn the headwaters of both are good 

 trout streams but these will not be interfered wdth. The flowed 

 lands include the lower and unimportant portions of the Caneadea 

 and Rush creeks which are now too warm for trout. Here, if con- 

 ditions warrant it, shallow, warm water s])ecies may be introduced. 



Personnel. — The staff in the field consisted of fourteen scien- 

 tists operating under the direction of the Conservation Dei)art- 

 ment with Emmeline Moore, Investigator in Fish Culture, in 

 charge. The work of the different experts covers the follow^ing 

 fields : Dr. Geo. C. Embody, environmental conditions as they 

 relate to the general ])roblem of a stocking policy; Mr. F. E. 

 Wagner, chemist, on ])roblems related to pollution ; Dr. P. W. 

 Claassen, biologist, on ])ollution studies; Mr. J. R. Greeley and 

 Dr. A. H. Wright, ichthyologists ; Ellen Edmonson, artist ; 

 Dr. W. C. Muenscher, botanist. Assistants on various problems : 

 Dr. D. J. Leffingwell, Messrs. A. L. Hazzard, R. P. Hunter, W. J. 

 Hamilton, Jr., P. E. Hering and F. K. Smith. Especial acknowl- 

 edgments are due Mr. J. P. Young, who identified the diatoms in 

 ])olluted and non]^olluted waters, and to the game protectors of 

 the region who gave substantial assistance in the investigation. 



Presentation of Data. — The data collected in these several 

 lines of inquiry are ])resented in the full report of the survey in 

 five sections, dealing with : 



(1) Stocking i)olicy for the Genesee river system. 



(2) Chemical investigation of the Genesee river system with 

 special reference to pollution. 



(3) Biological studies of i)olluted areas in the Genesee river 

 system. 



(4) Fishes of the Genesee region with annotated list. 



(5) The vegetation of Silver lake and Conesus lake.

Additional data of a detailed nature not incorporated in these 

 sections or in the appendices are filed in the office of the Conserva- 

 tion Department w^here they are accessible on request to all 

 interested in these investigations.
