Crappies
Crappies () are two species of North American freshwater fish of the genus ''Pomoxis'' in the Family (biology), family Centrarchidae (sunfishes). Both species of crappies are popular game fish among recreational fishing, recreational angling, 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 Mid-Atlantic US, 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 Fre ...

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] |

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 the ...

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 sunfish are highly valu ...

Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...

Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus '' Esox'' (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike in 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 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 (from the Middle English for 'pointed'). Various other unofficial trivial names are common pike, Lakes pike, great n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French Natural history, 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 (''Apalone mutica, 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 bat ...

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 s ... [...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 Ameri ...
