NOTES ON FISH-CULTURE IN GERMANY.

When the larvte have developed in the meat, the window is opened, so as to cause 
the larvae, through the influence of the light, to go to the bottom. A stream of water 
is now let in through a, which drives the larvae into the pipe c (fig. 2). Below this 
the trout gather in schools and watch for the food carried out with the water, with 
such eagerness that it is impossible for the larvae to escape their voracity. On this 
fare the young trout thrive marvelously, and grow large and strong. The greatest 
advantage, however, of this arrangement is in the circumstance that there is no 
refuse to render the water impure or actually dangerous for the young fish; which is 
greatly to be feared when young fish are fed on liver or similar articles of food. 
The so-called “feeding- wheel” consists of a cylindrical tin tray about 14 centi- 
meters (5£ inches) in diameter, and 5 centimeters (nearly 2 inches) deep (fig. 3). The 
outer rim of the cylinder is perforated at d d d (fig. 4), and is provided with paddles 
e e e e e. The cylinder is moreover provided with an axletree. As this rests on two 
supports, and as a stream of water is forced against the paddles in the direction 
of the arrow (fig. 3), the cylinder is made to rotate, which motion causes the finely 
ground food inclosed therein to be gradually ejected through the apertures d d d. 
The young fish, which soon find this out, gather under the wheel — the waterfall — and 
catch the food. This arrangement has all the greater practical importance in feeding- 
young trout, because, when the fish are fed by hand, they never get that portion of 
the food which falls to the bottom. 
THE COURSE OF INSTRUCTION OF THE BAVARIAN FISHERY ASSOCIATION . 1 
I had the pleasure of receiving an invitation from Professor Steuert, who is a 
member of the Bavarian Fishery Association, to attend its course of instruction, 
where both theoretical and practical instruction in fish-culture are given. The 
meeting was held in the old building of the Royal Academy of Fine Arts, in Munich. 
The excellent work of the association was spoken of, and attention was called to the 
fact that the results were not solely due to practical work, but also to the aid which 
the association had at all times received from the scientists of the Munich University. 
Waters which were formerly fishless had been stocked with suitable kinds with such 
success as to give them a perfect wealth of fish. 
A lecture by the well-known zoologist, Dr. Hofer, lasted from 10 a. m. to 7 p. m., 
with a recess of two hours. The lecture was in three parts: (1) Biological descrip- 
tion of the kinds of fish which form the subject of the association’s fish-cultural efforts; 
(2) the proper care and protection of the fishing waters; (3) fish-food. 
Among the fish which the association had cultivated the speaker mentioned: 
Carp, tench, perch, bass (American), eel, trout (rainbow trout), German brook trout, 
American brook trout, and Alsace trout (a cross between the American brook trout 
and the European trout), grayling, gwiniad, etc., and finally the pike. 
The speaker said that the carp was not indigenous to Germany, but was now 
found everywhere. He exhibited a number of select carp, which by cultivation had 
reached large and well-rounded dimensions, and which differed very much from the 
so-called peasant’s carp, a small and insignificant-looking fish. There are two kinds
