May be at once distinguished from the chub by its 

 much smaller scales,, and the different shape of the anal 

 fin, which in the ide is square or rather indented, in 

 the chub rounded off. Kroyer appears to doubt 

 whether the British ide is identical with the northern 

 fish. 



The ide is a very common fish in Scandinavia, from the 

 south of Sweden, at least as far up as Karesuando in Lap- 

 land, and the commonest of all the fresh-water fish in Fin- 

 land. They delight in clear and running water. Many 

 winter in the brackish bays of the Baltic, but they all come 

 up into fresh water to spawn, about the end of April. 

 Here they attain a good size, an ide of 5 or 6 Ib. not 

 being uncommon, and they are even said to become larger. 

 They will take a bait spinning. In habits they rather 

 resemble the British chub, but are far better eating. I do 

 not see why this fish should not be introduced into the 

 British waters, with profit, for I fancy they would thrive 

 in any chub water, and it is certainly a far better fish than 

 the chub. 



The specimen described by Nilsson was 17 in. long, 

 4^- in. high, weighing 24- Ib.

Much confusion has existed in the identification of 

 the chub, the dobule roach, and the dace ; but I believe 

 the synonymes which I have given all properly belong 

 to this fish. It was a matter of doubt for a long
