by adults. When thus separated into a rearing pond, 
development is rapid. For farm culture sorting is not 
necessary, but the yield of fish is certain to be much 
smaller than would be the case were sorting done and 
both a rearing and a stock pond maintained. During 
the hatching and nursing period these fish are excellent 
mothers and guard their young with unusual care and 
attention. Intruders are attacked savagely and driven 
away. 
8. Black bass—Of the larger varieties of black 
bass the two of most common importance in pond cul- 
ture are (1) the large-mouthed bass 
and (2) small-mouthed bass. On 
account of their habits and nature, 
they do not lend themselves often to 
pond culture under ordinary farm 
conditions. They are most at home 
in large bodies of water such as artificial reservoirs, 
lakes, rivers and large streams. Where pond culture is 
resorted to a relatively large area of ground is necessary. 
9. Black bass ponds.—Success with black bass is de- 
pendent upon a favorable site, properly constructed ponds 
and suitable water. These fish thrive in the same wa- 
ters with carp. The feeding habits, however, are differ- 
ent; black bass are carnivorous and depend upon other 
water animals for food. Young 
carp often are propagated in the 
same waters with black bass for the 
purpose of supplying the food. Be- 
cause of large area required and 
close attention to all details of man- 
agement, black bass are not commonly chosen for stock- 
ing small ponds or for use except as a commercial en- 
terprise of large proportions.
