TREATMENT OF THE YOUNG FISH. 



After the young fry leave their eggs, they 

 may be suffered to remain for a few days, in the 

 hatching hoxes, or they may be removed at once 

 into small tanks, or boxes, having fresh water 

 running through them ; the place where the water 

 enters, and where it makes its exit, being guard- 

 ed by wire cloth, to prevent the escape of the 

 rish. A box three feet long, by two feet broad, 

 and one foot deep, would be sufficiently large to 

 hold one or two thousand. When about two 

 7Tionths old, they should be placed in larger 

 tanks, or what would be still better, a pool of 

 water, fed by a good spring. It would be well 

 to have a nice, clean, gravelly bottom, with some 

 large stones thrown in, which would afford them 

 hiding places. If the pool could be shaded from 

 the rays of the sun, it would be much better, 

 as the water would be cooler, during the hot 

 days of summer. 



FOOD. 



The young fish need no feeding, for about 

 one month after they leave the egg. As they 

 draw, or receive their nutriment from the um- 

 bilical vesicle, or bladder, which is shown in the 

 cut, when this bladder, is absorbed, they will need 

 feeding, but only in small quantities, as the 

 surplus falls to the bottom, and decomposes.
