84 DOMESTICATED TROUT. 



The method of capturing the spawning fish is as 

 follows : A net of coarse bagging, six or eight feet 

 long, is made. The edges of the upper end of the 

 bag are fastened to a common wooden screen frame, 

 which then forms the mouth of it. This frame fits 

 into grooves made for it, at the lower end of the 

 spawning beds. The other or closed end of the bag 

 is made to taper somewhat, and an opening, say fif- 

 teen inches in length, is cut in it to let the fish 

 through into the spawning tub. This is to avoid 

 pouring them out from the upper end. This aperture 

 is tied up with a string before the bag is put in posi- 

 tion, and a large tub to receive the fish is placed on 

 the ground close to the outlet of the spawning bed, 

 where the bag will be placed. 



Now, having brought spawning pans enough to take 

 the spawn in, you approach the beds carefully with 

 the bagging in your hands. You slip the frame at the 

 mouth of the bag instantly into the grooves prepared 

 for it, and the spawning fish are trapped. You now, 

 with as little delay as possible, fill the tub half full 

 of water. Keep the spawning pans perfectly dry, place 

 them conveniently, and throw off the covers of the beds. 



The fish, with a little urging, will rush down stream 

 and hide in the bag. When they are all in, raise the 

 bag up quickly but gently, drop the lower end into 

 the tub of water, untie the string, and let them out. 

 If you have many fish and an attendant to help you, 

 it is a good plan to have two pails of water at hand, 

 and to have your attendant, while you are taking the 

 spawn, sort the males into one pail and the females
