The most taking bait is a small minnow, but grasshoppers, crickets, white grubs, or earthworms are good. In tidal waters the shrimp is preferred. But in the absence of any of these baits, cut-bait, either fish or flesh, may be used with good results, for the yellow-perch is not very particular or fastidious. Large perch are also easily taken by trolling with the minnow, or a very small spoon on lakes or ponds. If the spoon is employed, but a single hook should be used, and that not too large. I am not an advocate, however, for trolling for so small a fish, and merely mention it as one of the ways and means that may be followed. There are men who never rise above this method for any game-fish, but they are more to be pitied than blamed. They either lack the skill to practise more approved methods, or are too indolent to learn them. The yellow-perch has been introduced into some waters west of the Rockies. A few weighing about a pound were sent to me from a lake about forty miles west of Spokane, which were of exceptionally bright coloration and good flavor. In the same box were two pike of about four pounds each, and a large-mouth black-bass of eight pounds, dressed, and very fat, plump, and delicious. These fish were the result of a single plant by the United States Fish Commission some years ago. On the Missouri River, a few miles above the Great Falls, a large lake has been formed by an expansion of the river, caused by building a dam for an electric light plant. Several years ago some yellow-perch were placed in this lake, or in the river just above it, but by whom I have not been able to ascertain. At all events, the lake now swarms with perch, strings of one hundred or more not being an uncommon catch in a single day, as I am credibly informed. As the water above the forks of the Missouri River is too cold for the perch, and the water of the lake too warm for trout or grayling, there seems to be no probability of any harm resulting from the introduction of the yellow-perch, though it was not a wise thing to do. About the only fish in that portion of the Missouri, before the perch were planted just above the Great Falls, were ling, suckers, and catfish.
