The largemouth bass is an olive-green fish, in the North East, it most often has a gray color, marked by a series of dark, sometimes black, blotches forming a jagged horizontal stripe along each flank. The upper jaw (maxilla) of a largemouth bass extends beyond the rear margin of the orbit. In comparison to age, a female bass is larger than a male. The largemouth is the largest of the black basses, reaching a maximum recorded overall length of 29.5 in (75 cm) and a maximum unofficial weight of 25 pounds 1 ounce (11.4 kg). The fish lives 16 years on average.
The bluegill is noted for the black spot that it has on the posterior edge of the gills and base of the dorsal fin. The sides of its head and chin are a dark shade of blue. It usually contains 5–9 vertical bars on the sides of its body, but these stripes are not always distinct. It has a yellowish breast and abdomen. The bluegill has three anal spines, ten to 12 anal fin rays, six to 13 dorsal fin spines, 11 to 12 dorsal rays, and 12 to 13 pectoral rays. They are characterized by their deep, flattened bodies. The bluegill typically ranges in size from about four to 12 inches, and reaches a maximum size just over 16 inches.
Green Sunfish *Hybrid Bluegill
The green sunfish is blue-green in color on its back and sides with yellow-flecked bony-ridged (ctenoid) scales, as well as yellow coloration on the ventral sides. They also have a dark spot located near the back end of the dorsal fin and on the ear plate. Its pectoral fins are short with rounded edges containing 13-14 pectoral fin rays, a dorsal fin with about 10 dorsal spines and a homocercal tail. The typical length ranges from about 3-7 in and usually weighs less than a pound. The green sunfish reaches a maximum recorded length of about 30 cm (12 in), with a maximum recorded weight of 960 g (2.2 lb).
The black crappie (Pomoxis nigromaculatus) is a freshwater fish found in North America, one of the two crappies. It is very similar to the white crappie in size, shape, and habits, except that it is darker, with a pattern of black spots. Crappies have a deep and laterally compressed body. Black crappies have rows of dark spots.
The fathead minnow (Pimephales promelas) is a species of temperate freshwater fish belonging to the Pimephales genus of the cyprinid family. This minnow has also been introduced to many other areas via bait bucket releases. Its golden, or xanthic, strain, known as the rosy-red minnow, is a very common feeder fish sold in the United States and Canada. This fish is best known for producing Schreckstoff (a distress signal).
Muskellunge closely resemble other esocids such as the northern pike and American pickerel in both appearance and behavior. Like the northern pike and other aggressive pikes, the body plan is typical of ambush predators with an elongated body, flat head, and dorsal, pelvic, and anal fins set far back on the body. Muskellunge are typically 28–48 in (71–122 cm) long. According to past references the muskellunge attains 8 feet (244 cm) in length; this, however, has never been confirmed and is based most likely on exaggerations. A fish with a weight of 61.25 lb (27.8 kg) was caught in November 2000 in Georgian Bay, Ontario. The fish are a light silver, brown, or green, with dark vertical stripes on the flank, which may tend to break up into spots. In some cases, markings may be absent altogether, especially in fish from turbid waters. This is in contrast to northern pike, which have dark bodies with light markings. A reliable method to distinguish the two similar species is by counting the sensory pores on the underside of the mandible. A muskie will have seven or more per side, while the northern pike never has more than six. The lobes of the caudal (tail) fin in muskellunge come to a sharper point, while those of northern pike are more generally rounded. In addition, unlike pike, muskies have no scales on the lower half of their opercula.
Yellow perch is often recognized by its dark vertical stripes and gold or yellow body color. Perca is derived from early Greek for “perch” and flavescens is Latin for “becoming gold” or “yellow colored”. Adult sizes typically range from 3.9–11.4 in (10–30 cm); though have been known to grow larger. The yellow perch has a laterally compressed body with an oval, oblong shape. The anal fins are a green or yellow-orange, the dorsal fin is an olive color, and the belly is cream-colored. The vertical bands fade as they near the belly. Spawning intensifies the bands in males, and they can be nonexistent in juveniles. The spiny anterior dorsal fin has 13 to 15 spines. The soft rear fins also have one or two spines, but which are mostly made up of rays that range from 12 to 15 in number. The pelvic fins are close together, and the homocercal caudal fin is forked. The operculum tip has one spine, and the anal fin has two spines. There are seven to eight branchiostegal rays. Yellow perch has many fine and sharp teeth. They are rough to the touch because of their ctenoid scales. Common names for the perch are yellow perch, American perch, and lake perch. Yellow perch are one of the smaller-sized members of the perch family (Percidae). Yellow perch is one of the easiest fish to catch, and can be taken in all seasons, and tastes great. Therefore, it is a desirable sport fish in some locations of the US and Canada.
The brook trout has a dark green to brown color, with a distinctive marbled pattern (called vermiculation) of lighter shades across the flanks and back and extending at least to the dorsal fin, and often to the tail. A distinctive sprinkling of red dots, surrounded by blue halos, occurs along the flanks. The belly and lower fins are reddish in color, the latter with white leading edges. Typical lengths of the brook trout vary from 25 to 65 cm (9.8 to 25.6 in), and weights from 0.3 to 3 kg (0.66 to 6.61 lb). The maximum recorded length is 86 cm (34 in) and maximum weight 6.6 kg (15 lb). Brook trout can reach at least seven years of age, with reports of 15-year-old specimens observed in California habitats to which the species has been introduced. Growth rates are dependent on season, age, water and ambient air temperatures, and flow rates. In general, flow rates affect the rate of change in the relationship between temperature and growth rate.
The brown trout (Salmo trutta) is a European species of salmonid fish that has been widely introduced into suitable environments globally. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates stocks spawn on wind-swept shorelines of lakes. S. trutta morpha fario forms stream-resident populations, typically in alpine streams, but sometimes in larger rivers. What determines whether or not they migrate remains unknown.
Resident freshwater rainbow trout adults average between 1 and 5 lb (0.5 and 2.3 kg) in riverine environments, while lake-dwelling and anadromous forms may reach 20 lb (9 kg). Coloration varies widely between regions and subspecies. Adult freshwater forms are generally blue-green or olive green with heavy black spotting over the length of the body. The caudal fin is squarish and only mildly forked. Lake-dwelling and anadromous forms are usually more silvery in color with the reddish stripe almost completely gone. Juvenile rainbow trout display parr marks (dark vertical bars) typical of most salmonid juveniles.
Walleyes are largely olive and gold in color (hence the French common name: doré—golden). The dorsal side of a walleye is olive, grading into a golden hue on the flanks. The olive/gold pattern is broken up by five darker saddles that extend to the upper sides. The color shades to white on the belly. The mouth of a walleye is large and is armed with many sharp teeth. The first dorsal and anal fins are spinous, as is the operculum. Walleyes are distinguished from their close cousin the sauger by the white coloration on the lower lobe of the caudal fin which is absent on the sauger.
