Foods and Feeding of Fishes 147 



Mr. Buller : We have our bullhead breeding ponds as we call them, 

 we bring in our breeders in the fall of the year from the storage lakes 

 to which I have referred, and put them into the pond. The young cat- 

 fish are taken up into the rearing ponds and there they are fed until 

 October. 



Mr. Titcomb: What is the size of the breeding pond? 



Mr. Buller : About half an acre. In addition we also go on to the 

 storage dams and collect hundreds of thousands of catfish of the size 

 that you would get out of the rearing ponds. We only keep our rear- 

 ing ponds to guard against any unfavorable circumstance which would 

 prevent us gathering the fish at the proper time ; thus we make sure of a 

 supply of young fish. These young fish are fed sheep liver and milk; 

 they are voracious feeders and grow rapidly on that kind of food. We 

 have never experimented with or tried any other food, but we will 

 probably do so when we get around to it. However, we are getting 

 very good results from the sheep liver and the milk. 



Mr. Titcomb: You mean clabbered, soured milk? 



Mr. Buller: Yes. 



Mr. Adams: When you collect your fry either from outside or from 

 your central producing pond where you have your adult stock, how 

 much of a body of water do you put them in to rear them? 



Mr. Buller: Our ponds run from a quarter to half an acre each. 



Mr. Adams: How do you feed milk to these fish in bodies of water 

 that size? 



Mr. Buller: We put it around the shores and at the inlets. At 

 feeding time they will come to the troughs like a lot of bugs, and they 

 take a great deal of food. 



Mr. Adams : The first feedings are these feedings of clabbered milk? 



Mr. Buller: Clabbered milk and liver. 



Mr. Adams: You start right off with the liver as well as the milk? 



Mr. Buller: Yes. 



Mr. Adams: Do you feed the two at once, or do you give the liver 

 during the day and follow at night with the milk, as in the case of trout? 



Mr. Buller: We feed all our milk at night. Of course, we en- 

 deavor to have as much aquatic life in our ponds as possible. We never 

 disturb any of these ponds with a net- Before the ponds were arranged 

 as they are at present and the fish were taken out with a net, the re- 

 sult was destruction of a good deal of aquatic life 'n the ponds. They 

 are now so built, however, that we draw out our fish. 



Mr. Adams: How often during the day do you feed the small fish? 



Mr. Buller: They are fed morning, afternoon and evening. They 

 are practically feeding all the time. 



Mr. Adams: Ground up liver about the size you would feed to your 

 small trout? 



Mr. Buller : Yes, very fine when j'ou start, because they are small. 



Mr. Adams: You feed them on shore? 



Mr. Buller: On shore and at the inlets too.
