centre of its back the grayling can be easily recognised from all 
October 1908.

met with having a few 
dark spots near the gill- 
cover. Specimens I have 
had from the Itchen in 
Hampshire were more 
spotted and very much 
coarser than our Isla gray- 
ling. As the spawning 
season arrives much of 
the silvery appearance is 
lost, and they become of a darker colour all over. Grayling, like salmon, 
are very subject to disease, which carries them off in large numbers.
