=Trout.=--Trout, of which there are many species, are greatly prized both on account of their value as game fishes, affording sport for anglers, and because of their high palatable qualities. They belong to the same family as the Atlantic salmon and often it is difficult to distinguish by any of its common characteristics a trout from a salmon. This is especially true of trout of western America. The species of trout which are most highly prized on the Pacific coast are the cut-throat trout (_Salmo clarkii_), the rainbow trout (_Salmo iridens_), and the steel-head (_Salmo gairdneri_). The familiar silver trout of Lake Tahoe is another closely related species. They are distinguished by a remarkable system of spots of a circular form, black in color, and of varying size. The Lake Tahoe trout which is commonly secured is not the same as the silver trout of Lake Tahoe but is of a little different character, and is also known as the Truckee Trout, “Pogy,” and “Snipe.” It reaches a weight of from three to six pounds and is sometimes served on the dining cars of the Central Pacific Railway, in running through Idaho and into California. Various other species of the trout are found in Utah, in the Rio Grande and the Colorado, and in the lakes of Colorado. Perhaps the most important of these is the steel-head trout occurring along the Pacific coast. The rainbow trout is also a fish that is highly prized along the Pacific coast. The brook trout of western Oregon is also an important fish. _The Trout of the Great Lakes._--The fish known as trout in the Great Lakes belong to a different genus from those already mentioned, namely, genus _Cristivomer_. It has, however, the typical spots, which are of a grayish color instead of red or black like those of the other trout which have been mentioned. The principal species which abounds in the Great Lakes is the Mackinaw trout (_Cristivomer namaycush_). It is also found in the large lakes from Maine westward to the Pacific ocean and even to northern Alaska. This is the largest species of trout. The average weight of the fish probably does not exceed 15 or 20 pounds. Individual examples have been found weighing over 100 pounds. There is only one common fish which exceeds it in weight, namely, the sturgeon. Next to the white fish it is the most important commercial fish of the Great Lakes. The supply of lake trout has been diminishing and the price increasing for several years. The spawning season of lake trout begins in September and continues until December. _Composition of Lake Trout._-- FRESH. DRY.
