common on fish from the Mississippi 
River, and evidence seems to prove that 
they are to a degree seasonal in occur- 
rence. Under certain conditions they 
may cause serious injury to the host, but 
in the case of buffalo fish, and possibly of 
other species, it is believed that danger 
from infection in ponds might be les- 
sened by a proper rotation of the fish as 
the young seem to become infected from 
the adults placed in the same pond to 
spawn. 
A hitherto undescribed species of 
Coccidia is believed to have caused the 
death of young carp after transference 
from one of the ponds to hatchery 
troughs, as an exceptionally heavy infec- 
tion of the intestines with these parasites 
was associated with a serious degree of 
mortality. Although infection of the 
pond fish with the ciliate parasites Ich- 
thyophthirius, Chilodon, and Cyclo- 
chaeta was quite common, a much heavier 
infection after transference of the fish 
from the ponds to the tank house, prob- 
ably induced by change of environment, 
would seem to indicate that these para- 
sites have been largely responsible for 
the previous heavy mortality of the fish 
in the tanks.—Fisheries Service Bulletin.

Maruko is extremely delicate, but as a 
matter of fact, if carefully fed and kept 
in water at an even temperature, it is 
just as vigorous as other varieties 
more interesting. Under proper condi- 
tions it will live and enjoy life in the 
and 
aquarium for ten years or more. I have 
not seen a really fine example of the 
Maruko in the United States.

Plenty of Daphne during the warm 
months, but none when the thermometer 
registers zero. Be provident. Start a 
box of enchytraeid worms now. Next 
winter you will have an abundance.
