were in a cemented pool and there was nothing else there for them 

 to eat. I tried the same food on bass, but they did not grow satis- 

 factorily on this food exclusively. In the larger ponds where they got 

 a lot of natural food in addition to this, they did very well. 



Mr. Speaks: I wish to inquire as to the experience of the members 

 in placing some carp in bass ponds for food. Last year one of our 

 superintendents stripped two female carp, and in eight days had 

 400,000 young carp. If food that will suit the bass can be produced 

 in that way it would be a simple matter. 



Mr. Graham, of Massachusetts: When you once put carp into a 

 pond it is impossible ever to get them out again. If yon wish to 

 bring upon your head the condemnation of every fisherman, put the 

 carp in. 



Mr. Speaks: I know from one or two experiences that if bass are 

 introduced into water completely stocked with carp, it will be only 

 a matter of time until the carp disappear. They eat up all the young 

 carp. 



Professor Dyche: I do not favor carp. They eat up much of the food 

 that the little bass should have and they grow too fast. In the same 

 period a bass will grow to weigh a pound and a carp three pounds. 

 I prefer goldfish for food for bass. Young and small goldfish make 

 excellent food for young bass and larger goldfish are good for the 

 larger bass. 



But I do not want you to be misled by what I have said about feed- 

 ing. I have started out to found a hatchery where I will not have 

 to feed the fish and am working out every idea to make the ponds 

 self-sustaining. I have a great deal of vegetation in the ponds and 

 fish that will consume such matter and convert it into food for other 

 fish. I do not attempt to sort or remove small fish. Twenty thousand 

 of the larger fish eat up eighty thousand smaller ones, and that is all 

 right, as I get rid of the weaker bass that do not grow at a proper rate. 

 I have only 600 bass that I am feeding for a new stock of spawners. 



A Member: What is the preservative used in the fish food? 



Mr. Speaks: I do not know. It cannot be injurious because the fish 

 eat it every day and relish it. It is something to prevent the food from 

 becoming rancid. 



President Ward: How do they compare in growth with fish fed 

 on other foods? 



Mr. Speaks: We used only this food in one pond last year, and 

 after the pond was frozen over we put lines in and took out bass 

 eight inches long, which is a rather remarkable growth in one season.
