Liver proved to be out of the question, as the bass would 

 take only enough of it to keep them alive, and did not grow. 

 Beef was a little better, but expensive. Suckers were tried 

 with success, but as the source of supply was uncertain this 

 food was discontinued. Crayfish the bass would take in 

 almost unlimited quantities, and as we had an abundance oi 

 crayfish these were used almost wholly. Clam meat was 

 tried with equal success and an abundance of this food was 

 obtainable for the Mill Creek hatchery from the clam fisher- 

 men who supply the button factory with shells. 



Our fish were kept in a small pond about twenty by 

 forty feet, with natural sand sides and bottom. The cray- 

 fish after being run through a common meat grinder were 

 fed to the fish every two hours for the first several days and 

 they were given all they would eat at each feeding. After 

 several days they were fed only four times a day or about 

 every three hours. When fed in the above manner for four 

 weeks they attained a length of two inches, when they were 

 distributed. For lack of small ponds for rearing purposes 

 only 2,000 fish were fed in this way.
