88 FISH FARMING: 



fishery. The item of carriage alone of fry as compared with 

 carriage of eggs is an important one. Only in the case of hav- 

 ing a, hatchery and fry ponds of your own, and these close by 

 or actually on the water to b3 stocked, do I consider stocking 

 with fry to be a valuable as sowing fully-eyed ova ; even then 

 the " planting " must be very carefully done. However, you 

 may stock with fry, especially if it happens that you have no 

 suitable redds properly protected on which ten sow eggs, 

 and are!, therefore, compelled to resort to either fry or 

 yearlings. 



But in this connection an important matter crops up. 

 Different waters, or different portions of the same fishery, 

 vary considerably in depth, and the deeper the water to be 

 stocked the older the fry must be. This matter I deal with 

 fully in my remarks on rearing fry, and before stocking with 

 them you should refer to that chapter as well as this. This is 

 where the enormous value of a hatchery and fry ponds attached 

 to a fishery comes in, From them you can stock with fully- 

 eyed ovai, and then, in due season, first the shallows can be 

 treated with young fry; next the slightly deeper pants can 

 receive three-months fry ; after this the deep, slow water can 

 be stocked with six-months fry; and, finally, the remainder 

 of your fish in the rearing ponds may be cleared out and 

 planted in the fishery as yearlings. And while your fishery has 

 been in a continual state of receiving stock, your rearing ponds 

 have been prevented from becoming overcrowded. 



Mr. E. Valentine C'orrie is a firm believer in stocking with 

 fry, and in his hands several fisheries have been enormously 

 benefited after this manner. He goes so far as to assert that 

 in the case of some waters it is far and aiway the best method 

 of stocking, if persistently and thoroughly done. His experi- 

 ence of one water in particular is exceptionally interesting. It 

 was a neglected river, in which pike and other coarse fish had 

 been permitted to get the upper hand. It is to-day a prolific 

 trout stream. And this change has been brought about prin- 

 cipally by planting fry. Of course, pike were netted out each 

 year, and so gradually reduced in numbers, but long before
