Fish Food Used at Fish-Cultural Stations. 
AMOUNT AND COST OF FISH FOOD USED. 
The ideal condition sought by all fish-culturists is a water area 
so arranged that a natural food supply is available when needed, but 
from. our present knowledge the ideal is impossible of attainment in 
most cases and artificial feeding must be resorted to. In the rearing 
of fish under artificial environment, therefore, the problem of a sat- 
isfactory food supply at a reasonably low cost is ever present. 
The following table gives for the fiscal year 1921 the number of 
pounds and the cost per pound of artificial fish food used at the 
various fish-cultural stations during the fiscal year 1921:
