Regarding temperature, 75 degrees, 
Fahrenheit, suits this fish best, with a 
fluctuation of 5 degrees higher or lower 
as the limits of safety. 
The generic Acara is based on a name 
given this group of fishes by the natives 
of Brazil; tetramerus means divided into 
four parts, doubtless given because, to 
the describer, the dark markings seemed 
to divide the fish into parts. 
Propagating Daphne 
W. E. SCHAUMBERG 
The ordinary or “garden variety” of 
goldfish fancier is often at his wits’ end 
for Daphne for his young fish. Why not, 
‘therefore breed it in the back yard? 
Methods that have been described in the 
past are beyond the reach of the average 
‘ndividual because they involve too much 
space. Last year I solved the problem 
in so far as space is concerned, and man- 
aged to propagate sufhcient Daphne to 
supply the needs of 700 goldfish. 
I secured a cistern measuring six feet 
in diameter and two feet deep. On the 
bottom I spread three inches of garden 
soil. Then I prepared a galvanized 
wash tub in the following manner: A 
layer each of manure, wheat bran, 
ground oatmeal (about 10 quarts), then 
a few pieces of old meat and some gar- 
bage from the kitchen and a final layer 
of manure. The tub so prepared was 
placed in the cistern and covered with a 
piece of one-fourth inch mesh wire net- 
ting. This was weighted to hold the con- 
tents down and prevent interference 
when collecting the Daphne. The cistern 
was then filled with water, and a portion 
of Daphne placed therein to start the 
good work. 
Within a week the cistern was literally 
alive with them! When from constant 
netting they showed signs of diminishing, 
I boiled some oatmeal and corn meal to 
a paste, mixing it with about ten gallons 
of water before putting in the tank. In 
a few days the “Daph” were as numerous 
as before. I also found that cottonseed 
meal sprinkled on the water was appar- 
ently eaten by the Daphne. 
furnished a continuous 
supply of Daphne for my young fish 
throughout the summer, and saved me 
many a weary trip when the sun was hot. 
I kept it covered with mosquito netting, 
which excluded obnoxious insects and 
made it safe to transfer the Daphne 
direct to the rearing tanks without fear 
of introducing enemies among the fishes. 
This method is well worth a trial by the 
city man with a small yard. 
The cistern 
en 
The Bureau recently furnished small 
lots of eggs of the chinook and hump- 
back salmons for display at the aquarium 
maintained by Rothschild & Co., Chicago, 
Ill. This aquarium is visited daily by 
thousands of people. On the troughs 
containing the eggs memoranda were 
placed, showing the estimated pack of 
these species for the present season and 
information as to the value of canned 
salmon as food as compared with meats. 
On November 26 a miscellaneous assort- 
ment of over 8co fishes native to the 
Mississippi River was turned over in 
good condition to the Rothschild aqua- 
rium, the collection having been made in 
connection with the rescue operations 
conducted from the Bureau’s Homer 
(Minn.) station.—Fisheries Service Bul- 
letin.
