Crappie
Crappies () are two species of North American freshwater fish of the genus ''Pomoxis'' in the family Centrarchidae (sunfishes). Both species of crappies are popular game fish among recreational anglers. Etymology The genus name ''Pomoxis'' literally means "sharp cover", referring to the fish's spiny gill covers (opercular bones). It is composed of the Greek (, cover) and (, "sharp"). The common name (also spelled ''croppie'' or ''crappé'') derives from the Canadian French , which refers to many different fishes of the sunfish family. Other names for crappie are papermouths, strawberry bass, speckled bass or specks (especially in Michigan), speckled perch, white perch, crappie bass, calico bass (throughout the Middle Atlantic states and New England), and Oswego bass. In Louisiana, it is called sacalait ( frc, sac-à-lait, ), seemingly an allusion to its milky white flesh or silvery skin. The supposed French meaning is, however, folk etymology, because the word ...

Black Crappie
The black crappie (''Pomoxis nigromaculatus'') is a freshwater fish found in North America, one of the two types of 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. Taxonomy ''Pomoxis'', the genus name, is Greek: "poma, -atos" and "oxys" meaning sharp operculum. This references the fish's spined gill covers. The species name, ''nigromaculatus'', is derived from Latin and means "black-spotted". Description Black crappies are most accurately identified by the seven or eight spines on its dorsal fin (white crappies have five or six dorsal spines). Crappies have a deep and laterally compressed body. They are usually silvery-gray to green in color and show irregular or mottled black splotches over the entire body. Black crappies have rows of dark spots on their dorsal, anal, and caudal fins. The dorsal and anal fins resemble each other in shape. Both crappies have large mouths extending to below t ...

White Crappie
The white crappie (''Pomoxis annularis'') is a freshwater fish found in North America, one of the two species of crappies. Alternate common names for the species include goldring and silver perch. is named for the fish. The genus name ''Pomoxis'' refers to crappies' sharp operculum, while the species name ''annularis'' means 'having rings', i.e., it has vaguely vertical bars on the body. Description White crappies are morphologically similar to black crappie. They have 5–10 dark vertical bars along their bodies, rather than the randomly scattered spots like the black crappie. The white crappie has a silvery color with green or brown shades along its back, with dark lateral bars along its side, and a white belly. The dorsal fins of the white crappie starts farther back on the body than those of the black crappie. The anal fin is about the same size as the dorsal fin. The white crappie has six dorsal fin spines, whereas the black crappie has seven or eight dorsal fin spines. Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrarchidae
Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Perciformes (formerly belonging to the deprecated order Centrarchiformes), native only to North America. There are eight universally included genera within the centrarchid family: '' Lepomis'' (true sunfishes), '' Micropterus'' (black basses), ''Pomoxis'' (crappies), '' Enneacanthus'' (banded sunfishes), ''Centrarchus'' (type genus, consisting solely of the flier ''C. macropterus''), ''Archoplites'' ( Sacramento perch), '' Ambloplites'' (rock basses), and ''Acantharchus'' ( mud sunfish). A genetic study in 2012 suggests that the highly distinct pygmy sunfishes of the genus '' Elassoma'' are also centarchids. The centrarchid family comprises 38 identified species, 34 of which are extant. It includes many popular game fishes familiar to North American anglers, such as the rock bass, largemouth bass, bluegill, pumpkinseed, green sunfish and crappies. Most sunfis ...

Angling
Angling is a fishing technique that uses a fish hook or "angle" (from Old English ''angol'') attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muskellunge
The muskellunge ''(Esox masquinongy)'', often shortened to muskie, musky or lunge is a species of large freshwater predatory fish native to North America. It is the largest member of the pike family, Esocidae. Origin of name The name "muskellunge" originates from the Ojibwe words ''maashkinoozhe'' (meaning "great fish"), ''maskinoše'' or ''mashkinonge'' (meaning "big pike" or "ugly pike") and the Algonquin word ''maskinunga'', which are borrowed into the Canadian French words ''masquinongé'' or ''maskinongé''. In English, before settling on the common name "muskellunge", there have been at least 94 common names applied to this species, including but not limited to: ''muskelunge'', ''muscallonge'', ''muskallonge'', ''milliganong'', ''maskinonge'', ''maskalonge'', ''mascalonge'', ''maskalung'', ''muskinunge'' and ''masquenongez''. The word muskellunge is German and means "muscle lung". Description Muskellunge closely resemble other esocids such as the northern pike and ...

Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus ''Esox'' (the pikes). They are typical of brackish water, brackish and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike in Great Britain, Britain, Ireland, and most of Eastern Europe, Canada and the United States. Pike can grow to a relatively large size: the average length is about , with maximum recorded lengths of up to and published weights of . The International Game Fish Association, IGFA currently recognizes a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and typically grow to larger sizes in coastal than inland regions of Eurasia. Etymology The northern pike gets its common name from its resemblance to the pole-weapon known as the Pike (weapon), pike (from the Middle English for 'point ...

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle ('' Apalone spinifera''), smooth softshell turtle ('' A. mutica''), and common map turtle ('' Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet battalion at age fifteen and ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walleye
The walleye (''Sander vitreus'', synonym ''Stizostedion vitreum''), also called the yellow pike or yellow pickerel, 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 color morph 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. In parts of its range in English-speaking Canada, the walleye is known as a pickerel, though the fish is not related to the true pickerels, which are members of the family ''Esocidae''. Walleyes show a fair amount of variation across watersheds. In general, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
