FOR PLEASURE AND PROFIT. 85 



these fish; it only remains for me toi say, in this place, that 

 they should be introduced into the wa.ter if possible during 

 the winter time, or, at any rate, not later than March. After 

 that they have started to feed ftfeely on the fish-farm whence 

 they come, and, for this and other reasons, are less likely to 

 travel without injury. Such injury, I may add, is not always 

 evident on their arrival at their new home; but it has oc- 

 curred, none the less. 



It is quite common knowledge nowadays that fish should not 

 be transferred direct from the water in which they have tra- 

 velled into the water they are intended to stock. The two 

 waters should be gradually assimilated in temperature by the 

 repeated addition of some of the lake or stream water to that 

 in the fish carriers until that in the carriers has been raised 

 to the same temperature as that in the lake or stream. I say 

 raised, because, probably, the temperature in the carriers will 

 be lower than that of the water of the fishes' new home. But 

 it may be higher, although, except during a very severe frost, 

 it should not be. During a very severe frost it is inadvisable 

 to introduce fish. This objection does not occur in connection 

 with what I may term " frosty " weather, which is excellent for 

 travailing fish. One other hint : Purchase the yearlings from 

 a farm on wh'ch you absolutely know there is a plentiful sup- 

 ply cf natural food ; and do not make the mistake of thinking 

 that because a yearling tout is not six inches long it is 

 less valuable for stocking purposes. It may quite easily be 

 far more valuable, as I point out in my remarks on, artificial 

 feeding. 



Next to stocking with yearlings, the simplest plan is to 

 " sow " fully-eyed ova on natural or artificial redds, where they 

 exist, or where they have been formed and properly protected 

 after the manner I describe in the chapter on that subject. I 

 would repeat here that I consider this to be one of the most 

 effective and most economical methods of stocking waters 

 for sporting purposes. In the chapter referred to, I have dealt 

 fully with the manner in which these redds are utilised where 

 a stock of spawners exists. Now I propose to deal with ma.ni-
