Walleye (disambiguation)

Last updated April 22, 2019

Walleye is a freshwater fish native to most of Canada and the northern United States.

The walleye, also called the yellow pike, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a subspecies that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification.

Walleye may also refer to:

Blue walleye, a subspecies of walleye that became extinct in the 1970s
AGM-62 Walleye, a television-guided glide bomb used during the 1960s
Wisconsin Walleye War, a 1987–1991 episode of civil unrest over the hunting and fishing rights of Chippewas outside of their reservation
Toledo Walleye, a professional ice hockey team based in Toledo, Ohio
Conditions relating to eyes
- Strabismus, in which the two eyes do not point in the same direction
- a variety of heterochromia, in which one eye has a white or blue-ish white iris
- eyeshine, as of the walleye fish
Strabismus is a condition in which the eyes do not properly align with each other when looking at an object. The eye which is focused on an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia or loss of depth perception. If onset is during adulthood, it is more likely to result in double vision.
The tapetum lucidum is a layer of tissue in the eye of many vertebrates. Lying immediately behind the retina, it is a retroreflector. It reflects visible light back through the retina, increasing the light available to the photoreceptors. The tapetum lucidum contributes to the superior night vision of some animals. Many of these animals are nocturnal, especially carnivores, while others are deep sea animals.
Wall eye, one name for a horse's blue eye

The blue walleye, also called the blue pike, was a unique color morph of walleye which was endemic to the Great Lakes of North America. Morphometric studies led biologists to classify the blue walleye as a separate species in 1926, although it was later downgraded to a subspecies. Listed as an endangered species by the United States in 1967, it was declared extinct in 1983.

The AGM-62 Walleye is a television-guided glide bomb which was produced by Martin Marietta and used by the United States Armed Forces during the 1960s. Most had a 250 lb (113 kg) high-explosive warhead; some had a nuclear warhead. The designation of the Walleye as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the more modern GBU-15. The Walleye was superseded by the AGM-65 Maverick.

The Wisconsin Walleye War became the name for late 20th-century events in Wisconsin in protest of Ojibwe hunting and fishing rights. In a 1975 case, the tribes challenged state efforts to regulate their hunting and fishing off the reservations, based on their rights in the treaties of St. Peters (1837) and La Pointe (1842). On August 21, 1987, the U.S. District Court Judge Barbara Crabb ruled that six Ojibwe (Chippewa) tribal governments had the right under these treaties for hunting and fishing throughout their former territory.

In humans and most mammals and birds, the iris is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.

The sclera, also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the human eye containing mainly collagen and some elastic fiber. In humans, the whole sclera is white, contrasting with the coloured iris, but in other mammals the visible part of the sclera matches the colour of the iris, so the white part does not normally show. In the development of the embryo, the sclera is derived from the neural crest. In children, it is thinner and shows some of the underlying pigment, appearing slightly blue. In the elderly, fatty deposits on the sclera can make it appear slightly yellow. Many people with dark skin have naturally darkened sclerae, the result of melanin pigmentation.

The Maumee River is a river running from northeastern Indiana into northwestern Ohio and Lake Erie in the United States. It is formed at the confluence of the St. Joseph and St. Marys rivers, where Fort Wayne, Indiana, has developed, and meanders northeastwardly for 137 miles (220 km) through an agricultural region of glacial moraines before flowing into the Maumee Bay of Lake Erie. The city of Toledo is located at the mouth of the Maumee. The Maumee was designated an Ohio State Scenic River on July 18, 1974. The Maumee watershed is Ohio’s breadbasket; it is two-thirds farmland, mostly corn and soybeans. It is the largest watershed of any of the rivers feeding the Great Lakes, and supplies five percent of Lake Erie’s water.

Lake Nipissing is a lake in the Canadian province of Ontario. It has a surface area of 873.3 km² (337.2 sq mi), a mean elevation of 196 m (643 ft) above sea level, and is located between the Ottawa River and Georgian Bay. Lake Nipissing is the third-largest lake entirely in Ontario. It is relatively shallow for a large lake, with an average depth of only 4.5 m (15 ft). The shallowness of the lake makes for many sandbars along the lake's irregular shoreline. The lake reaches a maximum depth of 64 m near the mouth of the French River, off the shore of Blueberry Island. The lake has many islands most of which are protected under the Protection of Significant Wetlands scheme, controlled by the Ministry of Natural Resources and Forestry.

An odd-eyed cat is a cat with one blue eye and one eye either green, yellow, or brown. This is a feline form of complete heterochromia, a condition that occurs in some other animals, including humans. The condition most commonly affects white-colored cats, but may be found in a cat of any color, provided that it possesses the white spotting gene.

The silver lamprey is a lamprey commonly found in the Northern and Central United States, as well as a large part of southern Canada. Its binomial name means "sucking fish" in Greek and "one-pointed" in Latin. The silver lamprey is a member of the Class Agnatha, sometimes referred to as cyclostomes (round-mouths). Other common names include: Bloodsucker, Blue Lamprey, Hitch-hiker, Lamper, Lamprey Eel. The silver lamprey should not to be confused with the sea lamprey, which has caused considerable damage to native fish populations in the Great Lakes region.

Vision is an important sensory system for most species of fish. Fish eyes are similar to the eyes of terrestrial vertebrates like birds and mammals, but have a more spherical lens. Birds and mammals normally adjust focus by changing the shape of their lens, but fish normally adjust focus by moving the lens closer to or further from the retina. Fish retinas generally have both rod cells and cone cells, and most species have colour vision. Some fish can see ultraviolet and some are sensitive to polarized light.

Albinism is the "congenital absence of any pigmentation or coloration in a person, animal or plant, resulting in white hair, feathers, scales and skin and pink eyes in mammals, birds, reptiles, amphibians and fish and other small invertebrates as well." Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV and their lack of camouflage to avoid predators. Albino animals have characteristic pink or red eyes because the lack of pigment in the iris allows the blood vessels of the retina to be visible. Familiar albino animals include in-bred strains of laboratory animals, but populations of naturally occurring albino animals exist in the wild, e.g. Mexican cave tetra. Albinism is a well-recognized phenomenon in molluscs, both in the shell and in the soft parts. It has been claimed by some, e.g. that "albinism" can occur for a number of reasons aside from inheritance, including genetic mutations, diet, living conditions, age, disease, or injury. However, this is contrary to definitions where the condition is inherited.

The Pacific blue-eye is a species of fish in the family Pseudomugilidae native to eastern Australia. Described by Austrian naturalist Rudolf Kner in 1866, it comprises two subspecies that have been regarded as separate species in the past and may be once again with further study. It is a common fish of rivers and estuaries along the eastern seaboard from Cape York in north Queensland to southern New South Wales, the Burdekin Gap in central-north Queensland dividing the ranges of the two subspecies.
