their own offspring. In very narrow streams they 

 can sometimes be driven down, and into the 

 main river, and at this time of the year this is no 

 doubt the best plan. If they will not be frightened 

 away, a handy keeper will often succeed in 

 taking them out with an ordinary landing net. 

 If this plan is unsuccessful they should be driven 

 below the redds, and a short trammel dragged 

 down will usually secure them. It is in either 

 case well to carry them some distance from the 

 mouth of the carrier in which they have spawned. 

 Stress is laid here on not dragging over the 

 redds, although, unless the eggs are hatched, 

 probably no serious injury would accrue. 



On wide shallows of the main river nothing 

 but thorough netting is likely to be efficacious 

 when desiring to move fish after spawning. It 

 should not be resorted to unless absolutely 

 necessary, because it cannot be undertaken 

 before the early spring, and the tramping about 

 of men hauling nets does tend to make the fish 

 in the river shy. Besides, if the eggs are 

 hatched, it is likely to break up the schools of 

 young fry. As long as the fry keep together 

 they thrive, but when they get scattered by 

 artificial means, they usually drop down stream 

 and get into deep water, which is not suitable 

 for them, and holds a stock of their enemies — 

 either pike or large trout.
