MALACOPTERYGIOUS FISHES. 
Salmo salar.—The movements of Salmon are 
found to vary somewhat in different rivers. In the 
Ye aim, they are reported to spawn in winter, and 
the young are found to descend towards the sea in 
April. In the Plym also they descend in April, it 
occupying about three weeks for the entire fry to 
disappear. In one of the little streams leading to the 
Meavy above Shaugh bridge, a farmer once caught 
during night a large number ; where the stream is 
intercepted by a few blocks of stone placed across 
it he immersed a deep basket for two successive 
evenings ; into this the fish fell in great quantity, 
and were unable it seems to extricate themselves, 
as the man on each following morning took home 
his basket well filled. In the Avon they are re¬ 
ported to spawn later, and descend later ; they are 
considered to be in season at the time they are in¬ 
fested by lice. Are not equally numerous in all 
seasons. 
Salmo hucho .—Bull trout or Sea trout. (Turton 
and Kingston.) 
Salmo trutta.—“ Salmon peal." Migrations like 
the Salmon. They are often caught in the rivers by 
means of “ tickling.” 
Salmo fario .—Trout or Shot. In all our rivers, 
common. 
Coregonus thymallus.— Grayling. (Turton and 
Kingston.) 
Clupea harengus.— Herring. Off the coast in 
July, and the young are chiefly taken about 
November and December, at the mouths of rivers. 
Clupea pilcardus.— Pilchard. Abundant, except 
in an occasional year. In the years 1786—7, not a 
fish appeared off the Cornish coasts. For other 
particulars see observations in another part of this 
work.
