Mr. Adams: In the case of the bluegills, do you separate your fry 

 from your adult stock? 



Mr. Buller: No, we have our bluegills all in one place. We do not 

 separate the fry from the adults; we have not got to the point where 

 our room wfll allow that. Arrangements are now under way, however, 

 by which our present plant will be increased to the extent of about 

 forty per cent. 



Mr. Adams: Would you think it practicable to catch up the fry 

 from the larger ponds where you have your bluegills now stocked and 

 transfer them to the rearing stations as you would the hornpout? 



Mr. Buller: Yes, I think so. We would be doing it now if we 

 could. 



Mr. Adams: And you would feed the bluegills about the same way 

 you feed your horn pout — start them off with the clabbered milk and 

 then go on with the liver? 



Mr. Buller: Yes. 



Mr. Fleming: How many will you rear in one pond? 



Mr. Buller: The number varies. In the quarter acre and half 

 acre ponds we have anywhere from 80,000 to 300,000 fish. Some years 

 we are more successful than others. 



Mr. Titcomb: The average being about three inches? 



Mr. Buller: Two and a half to three inches. 



Mr. Adams: You plant these small bluegills in the fall? 



Mr. Buller: Yes. 



Mr. Titcomb: Can you raise as many bluegills in that pond as you 

 can bullheads? 



Mr. Buller: No. It requires more water for the bluegills than it 

 does for the catfish. You cannot grow them as you can the catfish. 



Mr. Titcomb: Is there much cannibalism among the blueg^ills? 



Mr. Buller: We do not notice it. I do not believe there is. 



Mr. Adams: Could you, at a given pond that houses, we will say, 

 the maximum number of brood stock in the spring, produce the maxi- 

 mum number of young bluegills which that pond is capable of hand- 

 ling? 



Mr. Buller: If the adults were not in there, no. 



Mr. Adams: In other words, you could supplement the stock which 

 you got from your adult fish by bringing in stock from the outside as 

 well. 



Mr. Buller: Yes, indeed. 



Mr. Burnham: Do your bluegills continue spawning all through 

 the summer? 



Mr. Buller: Yes, They are one of the long season fishes. What 

 we intend to do when the program is complete is to take these ponds 

 that contain the adult bluegills and the young fish, draw them out and 

 then retain the young fish until next October; they will then be a year 

 old before we let them go off the property. We believe that is the 

 right method to pursue, and that it will bring better results than we can
