12. Improved Methods of Water Weed and Algal Control. 



Experimental control of weeds and algae to determine best methods, using 

 newly developed herbicides and chemicals. 



Lakes in southern Minnesota; began June 1954, to close June 1956; E. J. 

 Longtin, Leader. 



Address inquiries to: John B. Moyle, as in No. 1 above. 



13. Reclamation of Small Lakes for Trout Management. (FA: F-3-D)* 



The objective of the project is to reclaim several small, former trout lakes 

 which have become overrun with such species as yellow perch, sunfish, pickerel 

 and walleyes which usually remain in a stunted condition and afford little fish- 

 ing. Following reclamation the lakes will be stocked with trout. 



Northeast part of State; began August 1952, indefinite; $3, 000; Jerome H. 

 Kuehn, Leader. 



Address inquiries to: John B. Moyle, as in No. 1 above. 



14. Statewide Creel Census. (FA: F-4-R)* 



The project objective is to obtain catch data on 12 selected lakes represent- 

 ing the varied conditions found in the State. The creel census is designed to 

 deternnine the total yield in numbers and pounds of game fish per lake. The 

 composition of the catch as to size and age groups will be determined and an 

 evaluation of the effects of natural reproduction and artificial stocking will be 

 made. 



Began December 1952, indefinite; $35,600; Don Franklin, Leader. 



Address inquiries to: John B. Moyle, as in No. 1 above. 



15. Fish Population Control. (FA: F-5-D)* 



Objectives of the project are to salvage fish from waters normally subject 

 to winter kill and drought, removal of excess populations of designated species 

 and stocking in waters where those species can be expected to thrive and con- 

 tribute to public fishing. 



Began May 195 3, indefinite; $25,906; Warren Kirsch, Leader. 



Address inquiries to: John B. Moyle, as in No. 1 above.

1. Distribution and Intraspecific Variation in Minnesota Fishes. 



Investigations are under way to determine the distribution of fishes in 

 various types of waters in Minnesota and to discover if any structural differ- 

 ences occur in the same species in different drainages. 



Began April 1952, to close September 1954; $200; James Underbill, Leader. 



Address inquiries to: James Underbill, Department of Zoology, University 

 of Minnesota, Minneapolis, Minn. 



2. Toxicity of the Eggs of the Longnose Gar. 



The project is concerned with the effect of feeding eggs of longnose gar to 

 various animals including fishes, and is attempting the isolation and identifica- 

 tion of the toxic agent present in the eggs of the longnose gar. The project is 

 continued to determine the toxicity of the eggs at different stages of their develop- 

 ment. 



University of Minnesota; began May 1952. to close September 1954; $500; 

 Samuel Eddy, Leader. 



Address inquiries to: Dr. Samuel Eddy, Professor of Zoology, Department 

 of Zoology, University of Minnesota, Minneapolis, Minn.
