Musky

Musky are known by a wide variety of trivial names including Ohio muskellunge, Great Lakes muskellunge, barred muskellunge, Ohio River pike, Allegheny River pike, jack pike, unspotted muskellunge, Wisconsin muskellunge and barred muskellunge.

What Do Musky Look Like
Musky closely resemble other Pike such as the northern pike and American pickerel in both appearance and behavior. Like other pikes, the body plan is typical of ambush predators with an elongate body, flat head and dorsal, pelvic and anal fins set far back on the body. Musky attain lengths of 2–5 ft and weights of over 66 lb. 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 sure way of distinguishing 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.

Where do musky live
Musky are found in lakes and rivers from northern Wisconsin and northern Minnesota through the Great Lakes region, north into Canada, throughout most of the St Lawrence River drainage and northward throughout the upper Mississippi valley, although the species also extends as far south as Chattanooga in the Tennessee River valley. Musky are also found in the Red River drainage of the Hudson Bay basin. They prefer clear waters where they lurk along weed edges, rock outcrops or other structure to rest. A fish forms two distinct home ranges in summer: a shallow range and a deeper one. The shallow range is generally much smaller than the deeper range. A musky will continually patrol the ranges in search of available food in the appropriate conditions of water temperature, pH and clarity.

What Do Musky Eat
Muskies prey upon anything that fits in the mouth. Most of the diet is fish but it also includes crayfish, frogs, ducklings, snakes, muskrats, mice and other small mammals. The mouth is large with many sharp teeth. Muskies take their prey head-first, sometimes in a single gulp. They will take prey items that are up to 30% of their total length. Very large specimens have been known to eat fully grown ducks.

Musky Behavior
Muskellunge are sometimes gregarious, forming small schools. They spawn in mid to late spring, somewhat later than northern pike, over shallow, vegetated areas. The males arrive first and attempt to establish dominance over a territory. Spawning may last from five to ten days and occurs mainly at night. The zygotes (eggs) are negatively buoyant and slightly adhesive; they adhere to plants and are then abandoned by the adults. Those embryos which are not eaten by fish, insects or crayfish hatch within two weeks. The larvae live on yolk until the mouth is fully developed, at which time they begin to feed on copepods and other zooplankton. They soon begin to prey upon fish. Juveniles will generally attain a length of 12 inches by November of the first year.

Musky spawning habits
Musky reach sexual maturity at 3–5 years with females maturing later than males. The fish may live to approximately 30 years of age. Females grow faster and live longer than males, and thus reach greater lengths and weights. While muskies in the northern portion of the range may take as much as 11 years to reach 40 inches in length, the fish in the southern portion of the range may attain such a length in as little as 5 years. Maximum size is heavily influenced by the genetics of a population. In general, maximum size increases with increasing northerly latitude.

Do Musky Have Predators
Few animals, save for large birds of prey and humans, prey upon adult musky's but juveniles are consumed by other muskies, northern pike, bass and sunfish. The musky's low reproductive rate and slow growth make populations highly vulnerable to overexploitation. This has caused some jurisdictions to institute artificial propagation programs in attempts to maintain otherwise unsustainably high rates of angling effort. There is also strong cultural pressure on anglers to practice catch and release when fishing for muskellunge.

Fishing For Musky
Anglers seek large muskies as trophies or for sport. The fish attain impressive swimming speeds but are not particularly maneuverable. The highest speed runs are usually fairly short. Muskies are known for their strength and for their tendency to leap from the water in stunning aerobatic displays. A challenging fish to catch, the muskie has been called "the fish of a thousand casts". Anglers most often use extremely large but otherwise conventional lures. The average lure is 8–12 inches long but longer lures of (14–26 inches are not uncommon in the musky angler's arsenal.

Subspecies and hybrids
Though interbreeding with other pike species can complicate the classification of some individuals, zoologists usually recognize from zero to three subspecies of muskellunge.

The Great Lakes (spotted) muskellunge is the most common variety in the Great Lakes basin and surrounding area. The spots on the body form oblique rows.
The Chautauqua muskellunge is known from the Ohio River system, Chautauqua Lake, Lake Ontario, and the St Lawrence River.
The clear or barred muskellunge is most common in the inland lakes of Wisconsin, Minnesota, northwestern Ontario and southeastern Manitoba.

The tiger muskellunge is a hybrid of the musky and northern pike. Male hybrids are almost invariably sterile although females are sometimes fertile. Some hybrids are artificially produced and planted for anglers to catch. Tiger muskies tend to be smaller than non-hybrid muskies but grow faster. The body is often quite silvery and largely or entirely without spots but with indistinct longitudinal bands.
