 Game and Fish Commission 



1. Game and Fish Laboratory Research 



This project consists of various activities including a study of fish diseases 

 and other causes of mortality, nnarking and tagging experiments, pollution 

 studies, diet investigations, and development of an electric bottom fauna 

 separator. 



Statewide; began July 1953, continuing; $31,200; George Post, Leader; '' 

 reports available. 



Address inquiries to: Wyoming Game and Fish Research Laboratory, 

 Chemistry- Zoology Building, University of Wyoming, Laramie, Wyoming. 



2. A Study of the Effect of Fertilization on Trout Growth in an Alpine Lake in 

 Wyoming 



During the past two summers preliminary studies of the chemical condi- 

 tions, plankton, bottom fauna production, and the food habits and growth of 

 fish in two adjacent alpine lakes have been conducted. Early in the summer 

 of 1956, inorganic fertilizer was added to one of these lakes while the other 

 was held as a control lake for comparison of over -all production and particu- 

 larly fish growth between the fertilized and unfertilized lake. 



South central Wyoming; began July 1954, to close January 1959; $1, 990; 

 George T. Baxter; Leader; reports available.

3. Trout Survival Studies 



The object of these studies is to determine sizes, species and time of 

 planting which will provide the greatest yield to the creel for various types 

 of waters. Emphasis is placed on two stream studies and one lake study. 

 Marked fish are planted. Evaluation is based on creel census and fish popula- 

 tion studies.
