96 Modern Fishciilture in Fresh and Salt Water. 



all good foods if cut or scraped and passed through the 

 sieve, which should be changed to a larger mesh as the 

 fish grow ; the soft part of clams and eggs of other fish 

 make excellent food for the very young trout, but the 

 eggs of hens will make filthy troughs on account of so 

 much of the yolk becoming dissolved and settling to the 

 bottom, and there decaying. 



On Long Island I found the bellies of soft clams quite 

 good, but returned to beef liver. As the suckers spawn 

 in early spring, their eggs should be good food for 

 baby trout, as I know that the flesh of suckers is for 

 adults. 



The food of the very young wild trout consists of the 

 newly hatched larvae of water-breeding insects and the 

 young of the smaller fresh water Crustacea, food that 

 we have no way of supplying in quantity, and my own 

 experiments, with half a dozen barrels of rainwater, to 

 breed "wigglers" (the larvae of mosquitoes) were suc- 

 cessful as far as producing good food for the fry went ; 

 but as it took them about five or six days to grow, only 

 one barrel could be strained each day, and the produc- 

 tion was only equal to the demands of a few hundred 

 fry, so that to carry it out on a scale sufficient to feed 

 50,000 would have made an imposing array of barrels 

 and involved great labor and expense. The beauty of 

 this kind of food is that it keeps until used, as well as 

 being most suitable and wholesome. 



Mr. Charles Hoxsie devised an automatic feeder for 

 trout fry, intended to dispense with hand labor. An 

 underflow wheel of 10 or 12 inches diameter was put 

 in the distributing trough and a crank of i inch moved 

 a I strip which was suspended by cords over the heads 

 of the troughs and gave it a 2-inch reciprocal move- 

 ment parallel to the distributing trough — a wire would
