MAKING A FISHERY.

Moving fish

 holes. 



When the trout work up into the carriers or 

 ditches, in anticipation of a Mayfly gorge, they 

 should be left there until the hatch is quite over 

 and the fall of the imago or spent gnat a thing 

 of the past. [It is, by the way, well to arrange 

 that the water level in these carriers should be 

 kept up during the Mayfly season, and the best 

 of sport will often be obtained in such plases.J 

 If, however, after the fly is over, they do not 

 make their way back, it is best to net them 

 out, and remove them into the wider water of 

 the main river, as otherwise they are only too 

 likely to fall a prey to poachers. Wherever 

 there is a risk of carriers or ditches in water 

 meadows getting dry, the fish should at every 

 opportunity, and especially just after the water 

 is drawn down, be taken out and transferred to 

 the main stream. 



As to the general tendency of fish to con- 

 gregate in deep hatch holes, the extent to 

 which they should be netted out and moved to 

 other quarters depends on the comparative 

 number of fish, and the size, depth, and general 

 character of each hatch hole. Trout do not 

 rise well in such places, but there is usually, 

 proportionately to its size, a far larger supply 

 of food in a hatch hole than in the reaches of 

 the stream. Probably this plentiful food supply 

 is the chief incentive to the trout to work
