СКАЧАТЬ sink a line down straight in a pasture through snow and through ice, and pull up a bright, slippery, dumb, subterranean silver or golden fish! It is curious, also, to reflect how they make one family, from the largest to the smallest. The least minnow that lies on the ice as bait for pickerel, looks like a huge sea-fish cast up on the shore. In the waters of this town there are about a dozen distinct species, though the inexperienced would expect many more.

      It enhances our sense of the grand security and serenity of nature, to observe the still undisturbed economy and content of the fishes of this century, their happiness a regular fruit of the summer. The Fresh-Water Sun-Fish, Bream, or Ruff, Pomotis vulgaris, as it were, without ancestry, without posterity, still represents the Fresh-Water Sun-Fish in nature. It is the most common of all, and seen on every urchin's string; a simple and inoffensive fish, whose nests are visible all along the shore, hollowed in the sand, over which it is steadily poised through the summer hours on waving fin. Sometimes there are twenty or thirty nests in the space of a few rods, two feet wide by half a foot in depth, and made with no little labor, the weeds being removed, and the sand shoved up on the sides, like a bowl. Here it may be seen early in summer assiduously brooding, and driving away minnows and larger fishes, even its own species, which would disturb its ova, pursuing them a few feet, and circling round swiftly to its nest again: the minnows, like young sharks, instantly entering the empty nests, meanwhile, and swallowing the spawn, which is attached to the weeds and to the bottom, on the sunny side. The spawn is exposed to so many dangers, that a very small proportion can ever become fishes, for beside being the constant prey of birds and fishes, a great many nests are made so near the shore, in shallow water, that they are left dry in a few days, as the river goes down. These and the lamprey's are the only fishes' nests that I have observed, though the ova of some species may be seen floating on the surface. The breams are so careful of their charge that you may stand close by in the water and examine them at your leisure. I have thus stood over them half an hour at a time, and stroked them familiarly without frightening them, suffering them to nibble my fingers harmlessly, and seen them erect their dorsal fins in anger when my hand approached their ova, and have even taken them gently out of the water with my hand; though this cannot be accomplished by a sudden movement, however dexterous, for instant warning is conveyed to them through their denser element, but only by letting the fingers gradually close about them as they are poised over the palm, and with the utmost gentleness raising them slowly to the surface. Though stationary, they keep up a constant sculling or waving motion with their fins, which is exceedingly graceful, and expressive of their humble happiness; for unlike ours, the element in which they live is a stream which must be constantly resisted. From time to time they nibble the weeds at the bottom or overhanging their nests, or dart after a fly or a worm. The dorsal fin, besides answering the purpose of a keel, with the anal, serves to keep the fish upright, for in shallow water, where this is not covered, they fall on their sides. As you stand thus stooping over the bream in its nest, the edges of the dorsal and caudal fins have a singular dusty golden reflection, and its eyes, which stand out from the head, are transparent and colorless. Seen in its native element, it is a very beautiful and compact fish, perfect in all its parts, and looks like a brilliant coin fresh from the mint. It is a perfect jewel of the river, the green, red, coppery, and golden reflections of its mottled sides being the concentration of such rays as struggle through the floating pads and flowers to the sandy bottom, and in harmony with the sunlit brown and yellow pebbles. Behind its watery shield it dwells far from many accidents inevitable to human life.

      There is also another species of bream found in our river, without the red spot on the operculum, which, according to M. Agassiz, is undescribed.

      The Common Perch, Perca flavescens, which name describes well the gleaming, golden reflections of its scales as it is drawn out of the water, its red gills standing out in vain in the thin element, is one of the handsomest and most regularly formed of our fishes, and at such a moment as this reminds us of the fish in the picture which wished to be restored to its native element until it had grown larger; and indeed most of this species that are caught are not half grown. In the ponds there is a light-colored and slender kind, which swim in shoals of many hundreds in the sunny water, in company with the shiner, averaging not more than six or seven inches in length, while only a few larger specimens are found in the deepest water, which prey upon their weaker brethren. I have often attracted these small perch to the shore at evening, by rippling the water with my fingers, and they may sometimes be caught while attempting to pass inside your hands. It is a tough and heedless fish, biting from impulse, without nibbling, and from impulse refraining to bite, and sculling indifferently past. It rather prefers the clear water and sandy bottoms, though here it has not much choice. It is a true fish, such as the angler loves to put into his basket or hang at the top of his willow twig, in shady afternoons along the banks of the stream. So many unquestionable fishes he counts, and so many shiners, which he counts and then throws away. Old Josselyn in his "New England's Rarities," published in 1672, mentions the Perch or River Partridge.

      The Chivin, Dace, Roach, Cousin Trout, or whatever else it is called, Leuciscus pulchellus, white and red, always an unexpected prize, which, however, any angler is glad to hook for its rarity. A name that reminds us of many an unsuccessful ramble by swift streams, when the wind rose to disappoint the fisher. It is commonly a silvery soft-scaled fish, of graceful, scholarlike, and classical look, like many a picture in an English book. It loves a swift current and a sandy bottom, and bites inadvertently, yet not without appetite for the bait. The minnows are used as bait for pickerel in the winter. The red chivin, according to some, is still the same fish, only older, or with its tints deepened as they think by the darker water it inhabits, as the red clouds swim in the twilight atmosphere. He who has not hooked the red chivin is not yet a complete angler. Other fishes, methinks, are slightly amphibious, but this is a denizen of the water wholly. The cork goes dancing down the swift-rushing stream, amid the weeds and sands, when suddenly, by a coincidence never to be remembered, emerges this fabulous inhabitant of another element, a thing heard of but not seen, as if it were the instant creation of an eddy, a true product of the running stream. And this bright cupreous dolphin was spawned and has passed its life beneath the level of your feet in your native fields. Fishes too, as well as birds and clouds, derive their armor from the mine. I have heard of mackerel visiting the copper banks at a particular season; this fish, perchance, has its habitat in the Coppermine River. I have caught white chivin of great size in the Aboljacknagesic, where it empties into the Penobscot, at the base of Mount Ktaadn, but no red ones there. The latter variety seems not to have been sufficiently observed.

      The Dace, Leuciscus argenteus, is a slight silvery minnow, found generally in the middle of the stream, where the current is most rapid, and frequently confounded with the last named.

      The Shiner, Leuciscus crysoleucas, is a soft-scaled and tender fish, the victim of its stronger neighbors, found in all places, deep and shallow, clear and turbid; generally the first nibbler at the bait, but, with its small mouth and nibbling propensities, not easily caught. It is a gold or silver bit that passes current in the river, its limber tail dimpling the surface in sport or flight. I have seen the fry, when frightened by something thrown into the water, leap out by dozens, together with the dace, and wreck themselves upon a floating plank. It is the little light-infant of the river, with body armor of gold or silver spangles, slipping, gliding its life through with a quirk of the tail, half in the water, half in the air, upward and ever upward with flitting fin to more crystalline tides, yet still abreast of us dwellers on the bank. It is almost dissolved by the summer heats. A slighter and lighter colored shiner is found in one of our ponds.

      The Pickerel, Esox reticulatus, the swiftest, wariest, and most ravenous of fishes, which Josselyn calls the Fresh-Water or River Wolf, is very common in the shallow and weedy lagoons along the sides of the stream. It is a solemn, stately, ruminant fish, lurking under the shadow of a pad at noon, with still, circumspect, voracious eye, motionless as a jewel set in water, or moving slowly along to take up its position, darting from time to time at such unlucky fish or frog or insect as comes within its range, and swallowing it at a gulp. I have caught one which had swallowed a brother pickerel half as large as itself, with the tail still visible in its mouth, while the head was already digested in its stomach. СКАЧАТЬ
