SEA-EROUT 
(Salmo trutta) 
THE sea-trout is one of the best sporting fish we have in Great 
Britain, and is, besides, of greater value than any others to those 
who are fortunate enough to possess waters that contain them. They 
are netted in great numbers in our rivers and in the sea, and when 
we consider the vast quantities that are sent not only to our own 
markets, but also to those on the Continent, the revenue derived from 
them must be very great. 
I consider the sea-trout distinct from the salmon and _ grilse. 
Any one who has the opportunity of observing them proceed up a 
river can prove this by the way in which they run. No matter what 
its size may be, the sea-trout always runs in a zig-zag fashion—first to 
the one side and then to the other. The salmon, on the other hand, 
runs in a straight direction. Another way of knowing the sea-trout 
is by counting the number of scales. There are fourteen from the 
adipose or dead fin to the lateral line. The salmon, on the other hand, 
as may be seen from the illustration has ten (Fig. 122). By counting 
the scales, then, is a simple way of distinguishing between them, 
and is so sure a guide that no mistake need be made. From the 
photographs of sea-trout, both large and small, which are given it will 
be seen that they vary a great deal. 
Having made a careful study of this subject for thirty years, and 
having collected all the information I could bearing upon it, | have 
come to the conclusion that the sea-trout is the same fish as that which 
is called white trout, bull-trout, gray trout, peel, sewin, brith-dail,
