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. 152). 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).
