portion of the application blank which describes the lake more 

 particularly, this office will be in a position to advise you as to 

 which species to select. The introduction of pickerel, bass and 

 trout to so small a body of water means that the pickerel and bass 

 would quickly destroy all of the trout. They would then prey 

 upon each other until it would be a survival of the fittest. For a 

 lake of that area neither pickerel nor bass is suitable. If the 

 waters are sufficiently cool, with a constant flow of cold water 

 through the lake, trout are recommended." 



SUMMARY. 



In summarizing, allow me to condense what I have said and to 

 add to it by making some specific recommendations. 



1. List the waters under your jurisdiction and establish a 

 permanent policy as to the species with which you will specialize 

 in each. 



2. Prohibit the introduction of any species of fish foreign 

 to the waters, unless approved by the commission, and also the 

 introduction of any species contrary to the established policy; 

 this to include connecting privately stocked and controlled 

 waters. 



3. Co-operate with the United States Bureau of Fisheries 

 in the adherence to a permanent policy as to the selection of 

 species for restocking waters in which both authorities are 

 interested. 



4. Give the commissioners power to exterminate and market 

 rough fish at any time and by any means, either directly or by the 

 issuance of licenses. By rough fish is meant those kinds which 

 are antagonistic to the maintenance of a successful, permanent 

 policy already decided upon. It is immaterial for statistical 

 results whether fish are taken by nets or by hook and line. How 

 fish are taken should be regulated according to local conditions 

 and effects upon property values. In this connection the value of 

 recreation, as an asset in its effect upon property values, must not 

 be under rated.
