FIFTF.KNIH ANNUAL MKETING. 83 



pose of the United States Fisli Commission from now on. Now. 

 one remark that Mr. Dunning just spoke to me about — he 

 thought that if you keep them in the troughs too long- they be- 

 come too much domesticated. Now, there is the point — you 

 want to keep them long enough until they grow so that you 

 have a good healthy fish, I mean a fish of two or three months 

 about. Keep them there as long as you see fit and put them in 

 vour pond and feed them. That is my idea of it, keep them 

 until you get a good healthy fish. We have had at Northville 

 probably twenty-five thousand trout from a year old and up- 

 ward, and next week shall probably plant one half of these fish. 

 Some of them are probably at least a foot long. 



Mr. Fairbank. — I have no doubt that these fish, kept until 

 they become a mature fish, say a year old, will live in Lake 

 (reneva, because there is enough food for them there, minnows 

 and young fish that they can eat ; but I don't believe that if 

 they spawn there that the young fry which they hatch would 

 ever come to maturity, because I don't think there is any food in 

 that lake for them. The object of my making these remarks is 

 that gentlemen when selecting a lake to put trout in, should 

 lo(jk to the matter of the food for the fry, the young fish, and 

 look particularly to the rock formation, the stone formation 

 about it I think that is the secret of it, and if you put your 

 young fish in, keeping them until they are six months or a year 

 old, and then put them in a lake where there is no food for the 

 ivy, it will never amount to anything. These mature fish will 

 gr(jw, but there will never be a second generation. 



Mr. Mather. — What Mr. Fairbank has said about planting 

 fish in suitable waters is no doubt true, and what Mr. Clark says 

 about raising these young fish is also true, but it has been my 

 experience that a young lake trout would prefer to have the tail 

 or fin of his brother, to anything you can offer him. These 

 little devils eat each other up. 



Dr. Hudson. — I would inquire if there are any more papers 

 to be read ? If there are not, of course the more discussion wc 

 have, the better. 



The Secretary. — Tiiere is but one more paper, and if it is in 

 order I will now read it.
