 Address inquiries to: Kenneth D. Carlander, as in No. 1 above. 



5. Fish Populations in Artificial Lakes. 



Growth and abundance of fishes in two state -owned lakes are studied annually 

 to determine population changes. Particular emphasis has been placed on a 

 study of effects of the greatly decreased turbidity of one lake. 



State Conservation Commission cooperating; Lakes Ahquabi and Red Haw 

 Hill; began June 1948, continuing; $2,500; Kenneth D. Carlander, Leader; reports 

 available. 



Address inquiries to: Kenneth D. Carlander, as in No. 1 above. 



6. Effect of Stream Conditions on Fish Populations. 



The present studies deal primarily with effect of drought and winter on fish 

 and bottom fauna, and with an evaluation of various gear for sampling fish popu- 

 lations. Studies on success of reproduction of minnows in relation to water levels 

 will also be continued. 



State Conservation Commission cooperating; Story and Boone Counties; began 

 June 1946, continuing; $2,500; Kenneth D. Carlander, Leader; reports available. 



Address inquiries to: Kenneth D. Carlander, as in No. 1 above. 



7. Management of Small Ponds for Fish Production. 



Annual observations are being made on ponds where attempts to correct 

 population balance have been made by adding finger ling and adult fish. Marking 

 and recovery methods of estimating fish populations are being tested to improve 

 the techniques.

8. Compilation of Data on Fish Growth and Biology. 



This project attempts to summarize all growth, length-weight, and similar 

 data on freshwater fishes of the United States and Canada and publishes tabular 

 summaries in a handbook and periodical supplements. 



State Conservation Commission cooperating; Iowa State College, Ames; 

 began January 1947, continuing; $1,000; Kenneth D. Carlander, Leader; reports 

 available are: "Handbook of Freshwater Fishery Biology" (1950), and First 

 Supplement, (1953).

1. Fish Population Control on Kanapolis Reservoir. 



In this 3, 400-acre reservoir a high percentage of the channel catfish popula- 

 tion is composed of small, slow-growing fish. During the summer, these fish 

 are lured into shallow areas by baiting with carp and buffalo which have been 

 seined from the reservoir. While the channel catfish are concentrated in the 

 baited areas, drag seines are used to catch them. These fish are transplanted 

 in various lakes over the State where natural reproduction is inadequate to 

 maintain a suitable fishery.
