The flounder is partial to sheltered coves and quiet bays, preferring bottoms of sand or mud, though sometimes it is found in rocky situations. It is sedentary in its habits, partially burying itself in the sand or mud, where it remains during the entire year, feeding on minute shells, crustaceans, worms, etc.
It spawns in the spring, during March and April. The eggs are very small, about thirty to the inch; and unlike those of most marine fishes they do not float, but are heavy enough to sink, forming bunches or clusters on the bottom, adhering to the weeds, etc., where they hatch in from two to three weeks. The fry swim upright, like other fishes, with an eye on each side of the head, but as they grow older they incline to one side, the under eye moving gradually to the upper side, so that at the age of three or four months both eyes are on the upper side, as the result of a twisting of the bones of the head. The right side, being constantly exposed to the light, becomes darker or colored, while the left side, being deprived of light, becomes pure white.
It is an excellent food-fish, its flesh being firm, white, and of good flavor; and as it is easily procured in winter when other fishes are comparatively scarce, it is a favorite at that season. It rarely grows to more than a foot in length or a pound in weight. As it can be caught in early spring, late fall, and winter, when other fishes are absent or not inclined to bite, the angler with light tackle may obtain considerable sport with this fish, as it will eagerly take almost any kind of natural bait. A bait-rod used for trout or black-bass or a light cane rod can be utilized, with very fine linen line, a three-foot leader, and hooks Nos. 7 or 8, on gut snells; a reel is not necessary, but is convenient. Using as light a sinker as possible, with clam or sandworm bait, the angler may be assured of success. The fishing may be done from a boat anchored at low tide on muddy or grassy flats, or from wharves or piers favorably located.
THE SMELT
(Osmerus mordax)
The smelts were formerly classed with the salmon family, but are now placed in a separate one, Argentinidæ, in which are included a number of allied species. To all external appearances the smelt is a true salmonid, and differs from the trouts and salmon chiefly in the form of the stomach and its appendages. The American or Atlantic smelt was first described by Dr. Mitchill, in 1815, from the vicinity of New York; he named it mordax, or "biting." Its habitat is along the Atlantic coast from the Gulf of St. Lawrence to Virginia, but it is most abundant northward. It is landlocked in a number of northern lakes.
The smelt is a very pretty, graceful fish, with a long, slender body, long, pointed head, and large mouth, with a somewhat projecting lower jaw. The small adipose fin, which is peculiar to all of the salmonids, is situated far back, opposite the end of the anal fin; the caudal fin is deeply forked. Its color is pale olive-green above, silvery below, translucent, with an obscure, longitudinal, broad, satin-like band along the sides. The fins are greenish, with a few punctulations.
The smelt enters the tidal rivers and brackish bays in the fall and winter in countless myriads, preparatory to spawning. It feeds principally on the small fry of other fishes, mostly at night, and along the shores in shallow water. It spawns in March, in both fresh and brackish water. The eggs are small, about twenty to the inch, and are adhesive. A medium-sized fish yields fifty thousand eggs, which hatch in two or three weeks, according to the temperature of the water, though usually in from sixteen to eighteen days. Though small, it is highly prized as a food-fish, having a delicate and delicious flavor. When fresh it emits an odor resembling that of cucumbers. Its usual size is from five to nine inches and weighing from two to four ounces, though occasionally reaching a foot or more in length. The smaller fish are more prized, the largest having a rank oily flavor. It is caught in large seines by fishermen and shipped fresh to the markets, and in winter is taken in great numbers with hook and line through the ice.
Smelt fishing is a very popular pastime along the East Coast in the fall and winter, as it is at a time when not many other fishes are to be caught. In the inland lakes it is, as has just been mentioned, caught with hook and line through holes cut in the ice; but this is tame sport compared with fishing in open water with very light tackle. The angler can utilize his trout fly or bait-rod, or if he prefers, a very light natural cane rod eight or ten feet long. A reel is not necessary. The line should be of the smallest size, linen or silk, though silk lines soon rot in salt water. A fine leader three or four feet long, with hooks Nos. 3 to 6, on single gut snells, are next in order. When the fish are swimming in schools near the surface, especially at night, a sinker need not be used; under other circumstances, and when the tide is strong, one of suitable weight should be added. The fishing is usually best on the flood tide, and almost any kind of bait will answer; but shrimp is best, though sandworms, very small minnows, or even earthworms are useful. Given the proper time and place, and with tackle and bait in readiness, it only remains to cast the baited hook, retrieve the fish, and so on ad infinitum.
