The calico-bass is found in the Great Lake region and the upper Mississippi Valley, and along the Atlantic slope from New Jersey to Florida and Texas. Its range has been considerably extended by transplantation, even to France, where it thrives well as a pond fish. It is a handsome fish, resembling in its general features and shape the sunfishes, but with a thinner body and larger fins. It has a long head and a large mouth, with thin lips and projecting lower jaw. The eye is large with a dark, bluish iris. Its fins are large and strong. It grows usually to eight or ten inches in length, weighing from half a pound to a pound, but occasionally reaches a foot in length and two or three pounds in weight. Its color is bright olive-green, with silvery reflections, darker on the back, and paling to the belly. In some localities it is of a much darker and purplish hue with brassy lustre. It is profusely covered with dark spots or blotches, as large as the finger-tips or "chincapins." The fins are mottled with pale spots on a darker or olive ground. It is gregarious, being usually found in schools, and prefers clear water. It is especially adapted to pond culture, and spawns in spring or early summer, according to locality; it prepares its nest in sand, gravel, or on a flat rock in the same way as the sunfishes. Its food is the same, also, though it is more partial to young fish. It is an excellent pan-fish but does not excel as a game-fish, for though a very free biter, it does not offer much resistance when hooked. However, with very light tackle it affords considerable sport, as it does not cease biting, usually, until most of the school are taken. The usual method of angling for this fish is from an anchored boat on ponds or small lakes, or from the bank. At times it rises pretty well to the fly, and trolling with a very small spoon is also successful on lakes. The lightest rods and tackle should be employed, with hooks Nos. 3 to 5 on gut snells. A small quill float is useful in very weedy ponds with mossy bottom. The best bait is a small minnow, though grasshoppers, crickets, crawfish, cut-bait, or worms are all greedily taken. Fly-fishing is more successful during the late afternoon hours until dusk. The flies should be trout patterns of coachman, gray drake, black gnat, Henshall, or any of the hackles on hooks Nos. 4 to 5.
