Foods and Feeding of Fishes 159 



can get your pond fully impregnated with the goldfish; then the young 

 bass, when you turn them in, will clean up the goldfish. It would seem 

 that these are the main problems connected with bass culture at the 

 present time. 



Dr. Osburn: Do you mean by the common sunfish, the green sun- 

 fish? The bluegill will not eat young bass? 



Dr. Embody: No, I refer to the one, named Eupomotis gibbosus. I 

 have my suspicions about the bluegills. I know they will eat young 

 bullheads as fast as they can capture them. 



Dr. Osburn: What do you think of the midge larvae versus the 

 mosquito larvae? 



Dr. Embody: I would prefer the midge larvae, but the question is 

 how to produce them in sufficiently large numbers to permit their being 

 fed to the bass. In fact, the mosquito larvae production experiments 

 are an outgrowth of our attempts to produce the midge larvae. Midge 

 larva is a superior food, and of course the adult midge would not do any 

 harm to our neighbors. But they would have to be produced by the 

 millions, and the question is how to do that. 



Dr. Osburn: In Ohio waters, judging by the stomach contents, 

 young fish from three-quarters of an inch to an inch and a half feed 

 very largely on midge larvae before they come to the minnow stage of 

 feeding.
