FISH HATCHING ON A MODEST SCALE 433 



As we have not contemplated the construction 

 of rearing ponds in connection with our supposed 

 hatchery a somewhat costly business things have 

 now reached a stage when two matters of importance 

 have to be considered. The first is, where are the fry 

 to be put ? And the second, how are they to be con- 

 veyed to the spot ? The first of these will, of course, 

 depend upon what kind of waters one has it in mind 

 to stock, and also whether we have been preparing to 

 stock them with sea-trout and salmon, or with trout 

 only. If salmon or sea- trout, or both, we may safely 

 put the fry into any clear, running stream. Wherever 

 there is gravel, running water, and marginal growth, 

 the fry will find both security and food and may safely 

 be left to themselves. Should our stock be trout, the 

 same principles will apply to the restocking of a river. 

 If, however, one is restocking a reservoir or natural 

 loch, local conditions require to be studied. Any small 

 feeders, if such exist, which promise to afford both food 

 and shelter will be the place to put the fry. They will 

 very soon fall back to the main sheet when they require 

 a wider space to range in. But if no feeders are avail- 

 able, the fry must be placed in the loch itself. When 

 this has to be done, a shallow sheltered side of the water 

 should be selected, and instinct will teach the young 

 fish how to protect themselves. Undoubtedly many 

 will fall victims to numerous enemies of all kinds, but 

 their numbers allow considerable margin for casualties. 



In any event the brood should be from 3 to 4 in.
