Next to the Lea, the Colne and Stour are the homes
of more species of Fish than any Essex stream. At
Sudbury, the fishing is well cared for and protected. The
same may be said of Bures, Nayland, and Dedham.
I think there are more followers of the gentle craft
plying their sport on the Stour than anywhere else in
the county, always excepting the Lea. This river
has another charm for anglers, inasmuch as many of
its coarse fish are plentiful and run to a large size.
I do not think Trout occur in it naturally—in fact,
I never heard of the capture of a fish of this species
in it at all, until the last few years. Again, excepting
the Lea, wherever Trout occur in any of our rivers,
they have been late introductions. Where introduced,
however, they appear to have thriven well. Another
species introduced in this river is the Wels (Silurus
glanis), which does not appear to occur in any other
Essex stream (cf. Essex Nat. vol. viii., p. 252). Pro-
bably, anglers generally will not be disposed to agree
with the remarks of Dr. Gunther, as quoted under its
name in this list (see p. 106).
