5. Carp Removal from Crab Orchard Lake. 



The object of this project was to investigate the practicability of removing undesir-

 very successful technique of management. 



Dept. of Conservation cooperating; began March 1952, indefinite; $5,000; a prelim- 

 inary publication is planned for the fall of 1953.
