152 SCIENCE OF FISHING. 



A small casting spoon is successful for large trout It 

 should be kept several feet beneath the surface and should be 

 drawn slowly in spurts of about three or four feet at a time. 



The methods of fishing for broojc trout given here apply 

 also to all other kinds of trout. Rainbow trout are fre- 

 quently taken by trolling and lake trout are nearly always 

 taken that way, as they are invariably found in deep water. 



One of the most important of the native salmon trouts 

 is the steelhead. It is found in the northwestern coast 

 streams living part of the time in salt water, and spawns 

 some in spring and others in the fall, at the heads of the 

 streams. On very rare occasions these fish, it is said, reach 

 a'weight of twenty pounds. In shallow water the steelhead 

 trout will rise to a fly, but the most of those caught with 

 hook and line are taken by trolling with a spoon bait in 

 deep water. Natural baits are also used, the favorite being 

 salmon roe. 



The German or brown trout has been introduced into 

 this country from Europe. These fish sometimes reach a 

 weight of fifteen pounds, but usually run from two to three 

 when full grown. The same methods of fishing as recom- 

 mended for brook trout should be employed, except that the 

 tackle should be a little heavier. They do not rise to a 

 fly as well as the brook trout. 



The rainbow trout, of which like the others described 

 there are a number of species, are native to the streams of 

 the Northwest. They have also been introduced into eastern 

 waters, and are now found in many streams of Wisconsin, 

 Michigan, New York, and southward. In some streams they 

 grow to a much larger size than in others, but all through 

 they grow larger than the eastern brook trout. They are 

 gamey fighters and are fished for in the same ways as the 

 brook trout. In the West they are taken quite often by 

 trolling.
