FOB PLEASURE AND PEOFIT. 23 



As a rule a stream presents some possibility for the forma- 

 tion of redds off it, as in Fig. 3, and, even if those redds have 

 to be half a mile or more away from the bank of the main 

 stream, it is preferable to their construction as in Fig. 6, 

 which plan should only be adopted when compulsory. 



In any case, do not let your redds be too large ; rather have 

 more occupying the same space. It is very useful to have 

 light, galvanised wire^netting frame at hand to place across 

 eaich redd and thus separate it from the others. The earliest 

 fish mount up to the top redd and may be confined there; 

 then the redd next below becomes the available spawning 

 ground ; and so' on, until all the series are occupied. If any 

 fish should spawn in the lower redds before the upper redds 

 alre occupied, then temporarily protect their eggs in the 

 manner explained later on in this chapter. As soon as the 

 fish have spawned on either redd they may be taken out. As 

 soon as all the- fish on the redds have spawned the light wire 

 frames may be taken away altogether, but the main screens 

 must remain in position for reasons already stated. 



The scarcity of natural redds, and neglect in the formation 

 of artificial redds in connection with many of our lakes and 

 ponds, are the cause, in a very large measure, of the depleted 

 state of those waters. I hope I have made clear the remedy. 

 In most cases its application is a simple matter ; but, of coursa, 

 there exist conditions that absolutely bar the rendering of any 

 assistance in the way of redds, and these must be dealt with by 

 other methods of stocking, of which I have something to say 

 later on. 



Having made and protected the reeds you have done well, 

 and your fishery is bound to profit from the little care and 

 attention you have given it, for, without doubt, protected 

 redds are far more prolific than those unprotected. There re- 

 main a few other useful hints to bei imparted. The first of 

 these is concerning shade. Fish eggs require shade, and 

 plenty of it, and it is equally necessary to the well-being of 

 the alevins and fry and, indeed, for that matter, is more or 

 less necessary throughout the whole conduct of a fishery. If
