White Perch
The white perch (''Morone americana'') is not a true perch but is a fish of the temperate bass family, Moronidae, notable as a food and game fish in eastern North America. In some places it is referred to as "Silver Bass". The name "White perch" is sometimes applied to the white crappie. Generally silvery-white in color, hence the name, depending upon habitat and size specimens have begun to develop a darker shade near the dorsal fin and along the top of the fish. This sometimes earns them the nickname "black-back". White perch have been reported up to in length and weighing . Although favoring brackish waters, it is also found in fresh water and coastal areas from the St. Lawrence River and Lake Ontario south to the Pee Dee River in South Carolina, and as far east as Nova Scotia. They are also found in the lower Great Lakes, Finger Lakes, Long Island Sound and nearby coastal areas, Hudson and Mohawk River system, Delaware Bay and Chesapeake Bay. It is also found occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Of The Great Lakes
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. M ...

Bait Fish
300px, Feeder Goldfish are common baitfish. Bait fish (or baitfish) are small-sized fish caught and used by anglers as bait to attract larger predatory fish, particularly game fish. Baitfish species are typically those that are common and breed rapidly, making them easy to catch and in abundant supply. Overview Examples of marine bait fish are anchovies, gudgeon, halfbeaks such as ballyhoo, and scad. Some larger fish such as menhaden, flying fish or ladyfish may be considered bait fish in some circles, depending on the size of the gamefish being pursued. Freshwater bait fish include minnows from the carp family (Cyprinidae), sucker family (Catostomidae), topminnows from the killifish suborder (Cyprinodontoidei), shad family (Clupeidae), sculpin of the order Scorpaeniformes and sunfish family (Centrarchidae), excluding black basses and crappies. Bait fish can be contrasted with forage fish. ''Bait fish'' is a term used particularly by recreational fishermen, although commer ...

White Perch GLERL
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches, ...

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands.

Glycera (genus)
The genus ''Glycera'' is a group of polychaetes (bristle worms) commonly known as bloodworms. They are typically found on the bottom of shallow marine waters, and some species (e.g. common bloodworms) can grow up to 35 cm (14 in) in length. Anatomy Bloodworms have a creamy pink color, as their pale skin allows their red body fluids that contain haemoglobin to show through. This is the origin of the name "bloodworm". At the 'head', bloodworms have four small antennae and small fleshy projections called parapodia running down their bodies. Bloodworms can grow up to in length. Bloodworms are carnivorous. They feed by extending a large proboscis that bears four hollow jaws. The jaws are connected to glands that supply venom which they use to kill their prey, and their bite is painful even to a human. They are preyed on by other worms, bottom-feeding fish, crustacea, and gulls. Reproduction occurs in midsummer, when the warmer water temperature and lunar cycle among other ...

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] |
Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more than 200 species in 11 genera. The perches, and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Characteristics The family is characterised by having the dorsal fin split into two which are normally separated or have a narrow connection, although this is wider in the genus ''Zingel'', the front section contains the spines and the rear section contains the soft rays. The anal fin contains 1 or 2 spines, if there is a second spine it is typically weak. The pelvic fins are placed on the thorax and have a single spine and 5 soft rays. They also have skeletal synapomorphies. The maximum size attaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
