1 8 VERMONT AGRICULTURAL REPORT. 



after, it begins to rise to the surface of the water for food and 

 snaps at floating particles. Unless you intend to feed the fry 

 and rear "fingerlings," ' I advise you to plant them when you 

 see the first one develop any symptoms of hunger, or just before 

 the sac is entire^' absorbed. You will then have carried the 

 eggs and fry through the least trying period of their existence 

 and brought them to a suitable age to plant with fairly good 

 results. 



TRANSPORTATION AND PLANTING OF FRY. 



If the waters to be stocked are near the hatchery, it may be 

 well to plant only a few each day, choosing the most active and 

 farthest developed ones. They can be transferred from trough 

 to pail or can on the scarf net without injur}'. At this stage, a 

 third scarf net made like either of the others except that the net- 

 ting should bag a trifle is useful. If attempting to stock a pond 

 and there are any tributary streams or any springs flowing into 

 it, plant at least a part near the springs. In stocking streams, 

 the same care in distributing fish should be observed, viz : that 

 the fry should be well scattered and placed in spring rivulets 

 which do not dry up. 



If the fish are to be transported a considerable distance, put 

 them in clean milk cans holding about ten gallons of water for 

 every three thousand fry. Five thousand can be carried 

 but the less crowding the better. Keep the water well iced. 

 When the cans are not kept in motion on the cars or in the wag- 

 on, aerate the water constantly by dipping it from the can and 

 then pouring it in again from a height of a foot or so from the 

 top of the can. Should there be a variation of more than six or 

 eight degrees in temperature between the water in the cans and 

 the water in which the fry are to be planted, dip water from the 

 can and from the stream or lake into the can until the temperature 

 of water in the can is brought to that of the stream or lake. Do 

 not, under an}- conditions, leave the can standing in the sun or 

 allow it to sit still more than five minutes unattended. 



CONCLUSION. 



The cost of two hatching troughs, with all necessary- equip- 

 ment for hatching 80,000 to 100,000 eggs should not exceed the 

 $1 8. 50 mentioned early in this chapter. The expense of con- 

 structing a hatchery building if that is necessary or of conduct- 

 ing a water supply to the hatchery is not included in this state- 

 ment. If } r ou wish tomake only a temporary experiment, con- 

 struct a trough of clear spruce boards. Use a barrel for a supply 

 trough. Melt a couple of tomato cans and perforate one sheet of
