COAESE FISH 



into a mill-pond at home, thinking that the fry 

 they produced would serve admirably as food to 

 the trout which also inhabited the pond. In 

 about twenty months the pond was full of small 

 rudd, and last year we netted out many hun- 

 dred, as the water was terribly over- stocked with 

 them. The same thing has happened in almost 

 every case which has come to my knowledge ; 

 that is, of course, where the waters have been 

 stocked with food, and suitable to the fish in- 

 troduced. 



The way in which dace will increase when 

 put into a suitable water is, if possible, even 

 more remarkable than what happens in the case 

 of the rudd. I will quote one instance, which 

 proves this very conclusively. A few years ago 

 there were no dace in the Sussex Ouse. Pike 

 fishermen, however, used to bring live dace to 

 use as baits. Some of these escaped, or were 

 set free by the fishermen at the end of their 

 day's fishing, and now the Sussex Ouse contains 

 more dace for its size than any other river I 

 have ever seen. 



While rudd thrive best in a pond or lake into 

 which a stream flows, dace require a river or 

 stream to do well. They will, however, thrive
