Originally, the small-mouth black-bass was restricted to the Great Lake region, parts of the Ohio and Mississippi valleys, and along the upper reaches of streams flowing from the Alleghany Mountains in the Southern states. It has, however, been introduced into all of the New England and Middle states, and into many Western states. It has a compressed, rather elliptical body, the dorsal and ventral outlines being nearly equal; it becomes deeper with age.
As its range, or distribution, is so great and extensive, and the waters it inhabits are so different in hue and character, the coloration of the small-mouth bass varies from almost black to the faintest tinge of green, in different sections of the country. The coloration is so variable that it differs even in fish in the same waters. It is influenced mostly by the hue of the water, character of the bottom, the presence or absence of weeds about the haunts of the bass, and, moreover, the changes in color may occur in a very short time when subject to these various conditions. The general color, however, is greenish of various shades, always darker on the back, and paling to white or whitish on the belly. When markings are present, they form vertical patches or bars, never horizontal. Three bronze streaks extend from the eye across the cheeks. All markings, however, may become obsolete with age.
The natural food of both species is crawfish, which might be inferred from the character of their teeth and wide-opening mouth. There is a popular belief that they are essentially and habitually piscivorous; but this is an error; they are not so black as they are painted. They feed on minute crustaceans and larval forms of insects when young, and afterward on crawfish, minnows, frogs, insects, etc., as do most fishes that have teeth in the jaws. But the teeth of the black-bass are villiform and closely packed, presenting an even surface as uniform as the surface of a tooth-brush. Such teeth are incapable of wounding, and merely form a rough surface for holding their prey securely. All truly piscivorous fishes have fewer, but sharp, conical teeth, of unequal length, like the yellow-perch, pike-perch, mascalonge, and trout, or lancet-shaped teeth like the bluefish.
The black-bass is far less destructive to fish life than any of the fishes mentioned; on the contrary, it suffers the most in a mixed community of fishes, and is the first to disappear. There are small lakes in Canada and Michigan where the brook-trout and black-bass have coexisted from time immemorial without jeopardy to the trout. There are small lakes in Wisconsin where black-bass and cisco, with other species, have coexisted for all time; and while the cisco is as numerous as ever, the black-bass has almost disappeared. It does not follow, however, that black-bass should be introduced in trout waters; far from it. Brook-trout are being exterminated fast enough, owing to the changed natural conditions of the streams and their surroundings, without adding another contestant for the limited supply of food in such waters.
Both species of black-bass have been introduced into Germany, France, Russia, and the Netherlands. In Germany, especially, they have found a permanent home. It was my privilege materially to assist Herr Max von dem Borne, of Berneuchen, with such advice as enabled him to start on a sure footing in his enterprise, and with such subsequent success in its establishment that he published several brochures on the black-bass to meet the demand for information as to its habits and merits as a game and food-fish. An effort was made some years ago to introduce the black-bass into English waters, but without success, owing to a want of knowledge as to the proper species to experiment with. The small-mouth bass was placed in weedy ponds or small lakes in which only the large-mouth bass would live.
The small-mouth bass thrives only in comparatively clear, cool, and rocky or gravelly streams, and in lakes and ponds supplied by such streams or having cold bottom springs. In lakes of the latter character, in northern sections, it coexists with large-mouth bass in many instances. In such cases, however, the small-mouth will be found usually at the inlet, or about the springs, and the large-mouth at the outlet or in sheltered, grassy situations. In winter it undergoes a state of partial or complete torpidity. In ponds that have been drained in the winter season it has been found snugly ensconced in the crevices of rocks, beneath shelving banks, logs, roots, or among masses of vegetation, undergoing its winter sleep. In the spring, when the temperature of the water rises above fifty degrees, the small-mouth bass emerges from its winter quarters, about which it lingers until the water becomes still warmer, when it departs in search of suitable locations for spawning. At this time, owing to a semi-migratory instinct, it ascends streams, and roams about in lakes or ponds, often ascending inlet streams, or in some instances descending outlet streams.
When favorable situations are found, the male and female pair off and proceed to fulfil the reproductive instinct. The spawning period extends from May to July, according to the section of the country it inhabits, and when the temperature of the water is suitable. The nests are formed on a bottom of gravel or coarse sand, or on a flat rock in very rocky streams. The male fish does the work of preparation by scouring with fins and tail a space about twice his length in diameter, forming a shallow, saucer-shaped depression, in which the female deposits her eggs, which are fertilized by the male, who hovers near by. The eggs are heavy and adhesive, being invested with a glutinous matter that enables them to adhere to the pebbles on the bottom. The number of eggs varies from two thousand to twenty-five thousand, according to the size and weight of the female. The nest is carefully guarded by the parents until the eggs hatch, the period of incubation being from one to two weeks, according to the temperature of the water. The resultant fry are then watched and brooded by the male fish for several days or a week, when they seek the shelter of weeds and grasses in shallow water.
The young fry feed on minute crustaceans and the larval forms of insects. When a month old they are about an inch long, and continue to grow, if food is plentiful, so that they reach a length of from three to six inches in the fall. Thereafter they increase a pound a year under the most favorable conditions, until the maximum weight is attained, which is about five pounds. In some instances, however, they have reached a weight of seven or even ten pounds, where the environment has been unusually favorable; notably in Glen Lake, near Glens Falls, New York, where a half-dozen or more have been taken weighing from eight to ten pounds. One of ten pounds was twenty-five and one-half inches long and nineteen inches in girth.
As a game-fish the black-bass has come into his inheritance. As the French say, he has arrived. With the special tools and tackle now furnished for his capture, he has proved my aphorism. "Inch for inch, and pound for pound, he is the gamest fish that swims." When I ventured this opinion twenty-five years ago, there were no special articles made for his capture except the Kentucky reel and the McGinnis rod, twelve feet long and fifteen ounces in weight. In awarding the palm as a game-fish to the black-bass, I do so advisedly, in the light of ample experience with all other game-fishes, and without prejudice, for I have an innate love and admiration for all, from the lovely trout of the mountain brook to the giant tarpon of the sea.
In the application of so broad and sweeping an assertion each and every attribute of a game-fish must be well considered: his habitat; his aptitude to rise to the fly; his struggle for freedom; his manner of resistance; his weight as compared with other game-fishes; and his excellence as a food-fish, must be separately and collectively considered and duly and impartially weighed. His haunts are amid most charming and varied scenes. Not in the silent and solemn solitudes of the primeval forests, where animated Nature is evidenced mainly in swarms of gnats, black-flies, and mosquitoes; nor under the shadows of grand and lofty mountains, guarded by serried ranks of pines and firs, but whose sombre depths are void of feathered songsters. However grand, sublime, and impressive such scenes truly are, they do not appeal profoundly to the angler. He must have life, motion, sound. He courts Nature in her more communicative moods, and in the haunts of the black-bass his desires are realized. Wading down the rippling stream, casting his flies hither and yon, alert for the responsive tug, the sunlight is filtered through overhanging trees, while the thrush, blackbird, and cardinal render the air vocal with sweet sounds, and his rival, the kingfisher, greets him with vibrant voice. The summer breeze, laden with the scent of woodland blossoms, whispers among the leaves, the wild bee flits by on droning wing, the squirrel barks defiantly, and the tinkle of the cow-bell is mellowed in the distance. I know of such streams in the mountain valleys of West Virginia, amid the green rolling hills of Kentucky and Tennessee, and in the hill country where Missouri and Arkansas meet.
