Address inquiries to: Arthur D. Bradford, as in No. 1 above. 



17. Culture of Muskellunge, Northern Pike, and Walleyes in Tanks 



Because past fish cultural work with these species in ponds resulted in 

 uncertain fish crops, experiments were designed to use steel tanks (22" x 

 22" X 10') for this purpose. 



Fry of all three species were fed daphnia. Fingerling muskellunge and 

 northern pike received live fish of suitable size as food and fingerling walleyes 

 were fed ground marine fish until planted in the fall. The fish were carefully 

 graded as to sizes.
