Foods and Feeding of Fishes 155 



Mr. Titcomb: Do you raise other warm water fishes than bass? 



Mr. Hayford: We have raised some perch and this year we tried 

 bluegills, but principally it has been the five species, rainbow, brook and 

 brown trout and large and small mouth bass. 



Mr. Titcomb: What do you feed to the bluegills? 



Mr. Hayford: Clam meal. The small mouth adult bass also eat it 

 ravenously. To the large mouth bass we give sheep's plucks; we can- 

 not get them to eat the clam meal. We turn that out a little larger; it 

 comes out the size of a pencil. 



Mr. Titcomb: Can you get plenty of clam meal? 



Mr. Hayford: We can get enough for our purposes — two or three 

 tons a year. Last year I think we got two tons. 



Mr. Titcomb: Do you think they eat the clam meal entirely? 



Mr. Hayford : They eat it ; they sit around waiting for it, you might 

 say. When you go down in the morning at ten o'clock to feed them, 

 they are all there waiting for it like a lot of hungry boys. 



Mr. Titcomb: Do you raise bullheads? 



Mr. Hayford: No, not to speak of. We have not any ponds for 

 that purpose as yet. 



Mr. Titcomb: How do you produce the mosquito larvae? 



Mr. Hayford: We put sour milk into concrete tanks five by thirty. 

 The mosquitos seem to fly up from all over the sections, and next 

 morning the place is all covered with mosquito eggs. 



Mr. Titcomb: Do the bass consume all the larvae you put in? 



Mr. Hayford: Mosquito larvae to bass are like candy to a child. 

 The reason we went into this mosquito larvae question arose out of a 

 paper given at Allentown, Pa., by Dr. Embody. We also have a lot of 

 the shrimp in our ponds; it is not the little fellow or the big one; it is 

 one of medium size. What is the name of the shrimp we have there at 

 Hackettstown, Dr.. Embody? 



Dr. Embody: I think it is the Caledonia shrimp; if not that, it is 

 one very closely related to it. 



Mr. Hayford: In the case of the large mouth bass, if we put min- 

 nows in with the sheep's hearts we always get a good fat fish. 



Mr. Titcomb: Do you raise minnows for food? 



Mr. Hayford: We have not made a business of raising minnows. 

 I may say that one year I put about fifteen thousand fry into a pond 

 50 feet wide by 160 feet long and from 2 to 3 feet deep. I put them 

 in on the 15th of June, and on the 16th of September we took out 

 5,702 fingerling small mouth bass from one to three inches long. It may 

 be said also that there does not seem to be much loss up to the three- 

 quarter inch and one inch period ; it is from there on that the loss 

 occurs. 



Mr. Titcomb : Do you find any particular kind of minnow preferable 

 to others? 



Mr. Hayford: What we have is largely the golden shiner. The 

 desirable thing, of course, is a slow moving fish; some of them move too 

 fast.
