MAKING A FISHERY. 



Netting a 

 hatch hole. 



Statistics. 



Salmonidce are often driven down by the 

 lowering of the water and the dragging of the 

 nets, a plan recently adopted with advantage 

 has been to net the hatch hole at the end of the 

 day's work, and return the trout or grayling 

 to the river above. The next morning's work 

 should commence with another netting of the 

 hatch hole, and, according to the views of the 

 lessee, the trout and grayling should either be 

 turned back above, or into the hatch hole 

 itself. 



When netting a hatch hole, the hatches 

 should be closed, to lower the water as much as 

 possible. If the shallow bar below the hatch 

 hole is almost dry a stop net is unnecessary, 

 but if there are four or five inches of water on 

 it the stop net should be set as usual. One of 

 the other nets, either the drag net or the 

 trammel only, will be required to clear the hole. 

 After splashing or poking any fish out from 

 under the apron the net should be dropped in 

 close to it and steadily drawn round to the stop 

 net ; hauled, emptied, and cleaned. This should 

 be repeated as often as any pike are secured ; or, 

 if it is desirable to move trout out of it, as long 

 as there are trout in the net. 



The following table is an accurate record of 

 the results of careful netting of a length of 

 trout water for the years 1893 and 1894. For
