FISH CULTURE IN CENTRAL EUROPE. 



571 



It is a wooden canal with a smooth bottom, wifih wooden partitions 

 (not shown in the figure) placed at regular intervals; the entire length 

 is 5.07 meters [16|- feet]; it is divided in two arms (A, B) of nearly equal 

 length, and connected by a horizontal arm (C) ; the first in the beginning 

 runs horizontal, and afterwards slopes towards the arm C ; and from this 

 again slopes the arm B, which widens at its end. It is clear that this 

 canal will conduct a current of water from a higher to a lower level. 



I am not able, however, to understand what benefit can be derived 

 from the use of this apparatus, which will not increase the "mounting" 

 of the eels (which in my opinion cannot be accomplished by any contriv- 

 ance whatever); but which will draw some of them away into water- 

 courses, which, owing to the lack of communication with the streams by 

 which the young eels usually ascend, would under ordinary circum- 

 stances not have them. 



The following table will show what fish, not belonging to the sal- 

 monoids, are cultivated in the establishments which I visited :
