What becomes of our young fish when the cold season approaches, 
when in October their power of moving decreases, till the period when 
they commence their long winter sleep? Ifthe spawning-pond is suited 
for wintering, where there is no danger of its being covered so thickly 
with ice as to cause the death of the young fish, it will be best not to 
take them out till spring, when the ice has melted, and when it is cer- 
tain that the pond can again be filled at the right time. 
If the young fish cannot winter in the pond, they may get through 
the winter by being placed in a so-called “ chamber-pond” which is free 
from fish of prey, and can be laid entirely dry; or, if this should be 
‘impossible, the 60,000 young fish°may safely be set free in October. 
_ We know the dangers to which they are exposed in waters containing 
many fish of prey, but we also know from experience that, in spite of 
this, successful results may be looked for. While, during winter, the 
-young fish are in a lethargic condition and the fish of prey are par- 
ticularly voracious, these latter are in spring in a very lazy condition, 
. owing to their having spawned, whilst the carp are lively and have an 
excellent appetite. From principle, therefore, it is much better to set 
out young fish in spring, although the setting out of one summer’s young 
fish is by no means as hopeless an undertaking as is thought by many 
pisciculturists. I will give an example from my own experience. One 
of my lakes, the Hamelung Lake, measures about 5 hectares, and con- 
tains numerous pike and perch. In autumn I stocked this pond with 
1,200 one-summer’s carp, and three years later I caught, during the ice 
fisheries, 680 table carp, which on an average weighed 3 pounds each. 
During the two previous winters the pike, caught during the ice fisher- 
ies, invariably threw up small carp, which they had evidently swallowed 
durizg the fisheries, because they had not yet been digested. I obtained: 
similar favorable results in several other lakes and in the river Mietzel, 
all of which waters are rich in pike and perch. I have, therefore, come 
to the conclusion that one hectare of water, which contains many fish of 
prey, can, even in autumn, be sufficiently stocked with carp, by placing in 
it 250 one-summer’s carp. ‘The fear, so often expressed, that such small 
fish would all be devoured by fish of prey, is in my opinion entirely 
groundless, because all large fish have, at some time during their life, 
been small, and been exposed to the danger of being devoured by larger 
fish. 
The larger the carp the smaller may be the number of fish placed in 
one pond. It will also pay to place large carp in open waters, for a 
very intelligent pisciculturist in Schleswig-Holstein has for a long time 
been in the habit of buying a large number of carp measuring 20 centi- 
meters or more in length, and stocking, with these fish, lakes where 
fishing is easy; and has in this way become a wealthy man. Thus he 
set out, last year, carp weighing 14 pounds each, and has been able, 
this winter, to catch fish weighing 24 pounds each. 
Throughout our entire country people begin to take a greater inter-
