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



This census is being conducted as a field survey by wardens, with statistical data 

 being compiled and analyzed for use in planning future seasons and development 

 and management procedures. 



Statewide; began July 1951, planned for 3 years; $2,600; Clinton G. Bishop, Project 



Leader.

4. Trout Disease and Nutrition Study (FA: F-8-R). 



The objective of this project is to determine the nutritional requirements of the 



various species of hatchery reared fish through the study of available literature 

 on the subject, chemical analyses, etc. Experiments will be made with various 

 diets including commercial products and rough fish. Studies are also being 

 made to detect fish diseases, testing of methods of treatment, and means of 

 disease control. 



Statewide; Chemistry Dept. of Montana State College cooperating; began December 



1951, planned for 3 years; $7,400; Jack E. Bailey, Project Leader.

5. The Contribution of Hatchery Reared T out to the Total Catch (FA: F-5-R, 

 F-7-R, F-9-R). 



This project is designed to measure, under various conditions, the relative contri- 

 bution to the creel of hatchery-produced and wild trout. Total creek census is 

 not made, but spot checks are made in sufficient volume to assure significant 

 results .

6. Cataloging the Lakes and Streams of Montana (FA: F-5-R, F-7-R, F-9-R). 



The purpose of this project is to determine the chemical, physical and biological 

 characteristics of the waters of the State. Emphasis is placed on those waters 

 which are most important to recreational fishing. Depending upon the water 

 involved, qualitative and/or quantitative measures of trout stream populations 

 are made by electric fish census methods.

7. Effectiveness of Smith Lake Rearing Pond (FA: F-7-R). 



The primary objective of this project is to measure the economics of the operation 

 of Smith Lake as a cutthroat trout rearing pond. The cost of the installation, the 

 cost of the fry planted, the cost of the operation are compared with the value of 

 the yearling trout produced. Production figures are obtained by draining the 

 pond and by making actual counts of the fish captured.
