In fishing for pike-perch in different parts of the country I have noticed its variableness of coloration, which might be inferred from some of its names, as gray pike, yellow pike, blue pike, white salmon, etc. As I remember them, those caught in brackish water in Maryland were quite greenish, with silvery reflections and with dark markings. On Lake Erie the coloration varies somewhat with age, the younger ones being known as blue pike, the mature fish as yellow pike, and the oldest and largest as gray pike. On the rivers of the Middle West that are subject to periods of high and muddy water they are much paler. On the many pine-fringed lakes in northern Wisconsin and Minnesota the variation in color is quite apparent, both as to the ground color and markings. The older fish are very dark and dull on the back, and the younger ones much brighter.
THE SAUGER
(Stizostedion canadense)
The sauger was first described by C. H. Smith, in 1834, who named it canadensis, from having collected his type specimens in Canada.
It is also known as jack, sand-pike, gray-pike, and rattlesnake pike. It is closely related to the pike-perch, though smaller and more slender, with a more pointed head and smaller eye. It is distributed through the Great Lake region and in the upper portions of the Missouri, Mississippi, and Ohio rivers. It grows to a length of twelve to fifteen inches. Its color is paler than the pike-perch, grayish above, with brassy sides, which are marked by several blackish blotches or patches, hence "rattlesnake pike."
It is not nearly so good a food-fish as the pike-perch, and is not of much importance as a game-fish. It may be fished for with the same tackle as that recommended for the calico-bass or crappie, in the same situations mentioned for the pike-perch. I have taken it with a gaudy fly on the Ohio and Muskingum rivers, in Ohio, and in the Big Sandy and Tygert Creek, in Kentucky; also by still-fishing and trolling on Lake Erie about the Bass Islands. The meaning or etymology of the name "sauger" is unknown.
THE YELLOW-PERCH
(Perca flavescens)
The yellow-perch was first described by Dr. Mitchill in 1814, from the vicinity of New York. He named it flavescens, "yellowish," owing to its coloration. It is closely allied to the perch of Europe. It is commonly known as perch or yellow-perch, also as ringed-perch and raccoon-perch. It is abundant in the Great Lake region and in coastwise streams of the Atlantic slope from Nova Scotia to North Carolina. It is also common in some of the tributaries of the upper Mississippi River and in certain lakes in northern Indiana. It is a handsome fish, well proportioned, and of a lively disposition. It has a shapely body, with a depth of about one-third of its length, somewhat compressed, and with an arching back. The mouth is moderate in size, with bands of small, bristlelike teeth, but no canines, and has a projecting snout. The head is not quite one-third of the length of the body. Its back is dark olive, sides bright golden yellow, belly pale or pinkish, with half a dozen or more broad, dark, vertical bars. The lower fins are bright red or orange. While the coloration varies somewhat in different situations it is always brilliant, rendering it one of the handsomest fishes among the fresh-water species.
The yellow-perch is gregarious, always in schools, and the fish of a school will be about of a uniform size, be that great or small. It frequents waters of a moderate depth in streams or lakes or ponds. In streams, early in the spring, it frequently resorts to the edge or foot of riffles, when feeding, but later prefers the deeper water under mill-dams and about the submerged timbers of bridges, and the still water under hollow banks, or in the eddies of old logs, rocks, etc. It is averse to a muddy bottom in fresh water, but along the eastern coast it is often found on the weedy shoals of shallow bays in brackish water. In my boyhood days it was a prime favorite with myself and companions. We sought it on the mud-flats, among the water-plants, of the Patapsco River, near Baltimore. It was there known as "yellow Ned," and was considered a good pan-fish.
