Atlantic Menhaden
The Atlantic menhaden (''Brevoortia tyrannus'') is a North American species of fish in the herring family, Clupeidae. Atlantic menhaden are found in North Atlantic coastal and estuarine waters from Nova Scotia south to northern Florida. They are commonly found in all salinities of the Chesapeake Bay and Mid-Atlantic water. They swim in large schools that stratify by size and age along the coast. Younger and smaller fish are found in the Chesapeake Bay and southern coastline while older, larger fish are found along the northern coastline. Characteristics Atlantic menhaden are silvery coloured fishes characterized by a moderately compressed body and a black spot on their shoulder behind their gill openings. They can reach a size of approximately 15 inches. Biology Diet The Atlantic menhaden is a filter feeder, which that it collects food by filtering water through modifications of the branchial apparatus (gill arches and gill rakers). Its diet depends on the size of their gill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eagle
Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Reduction Fishery
Reduction fisheries are fisheries that "reduce," or process their catch, into fishmeal and fish oil. They rely largely on small and medium-sized pelagic species; that is, fish found in the upper layers of the open sea, such as menhaden, anchovies, and sardines "Sardine" and "pilchard" are common names for various species of small, oily forage fish in the herring family Clupeidae. The term "sardine" was first used in English during the early 15th century, a folk etymology says it comes from the Ital ....

Tragedy Of The Commons
Tragedy (from the grc-gre, τραγῳδία, ''tragōidia'', ''tragōidia'') is a genre of drama based on human suffering and, mainly, the terrible or sorrowful events that befall a main character. Traditionally, the intention of tragedy is to invoke an accompanying catharsis, or a "pain hatawakens pleasure", for the audience. While many cultures have developed forms that provoke this paradoxical response, the term ''tragedy'' often refers to a specific tradition of drama that has played a unique and important role historically in the self-definition of Western civilization. That tradition has been multiple and discontinuous, yet the term has often been used to invoke a powerful effect of cultural identity and historical continuity—"the Greeks and the Elizabethans, in one cultural form; Hellenes and Christians, in a common activity," as Raymond Williams puts it. From its origins in the theatre of ancient Greece 2500 years ago, from which there survives only a fractio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilgrim (Plymouth Colony)
The Pilgrims, also known as the Pilgrim Fathers, were the English settlers who came to North America on the ''Mayflower'' and established the Plymouth Colony in what is today Plymouth, Massachusetts, named after the final departure port of Plymouth, Devon. Their leadership came from the religious congregations of Brownists, or Separatist Puritans, who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands. They held many of the same Puritan Calvinist religious beliefs but, unlike most other Puritans, they maintained that their congregations should separate from the English state church, which led to them being labeled Separatists (the word "Pilgrims" was not used to refer to them until several centuries later). After several years living in exile in Holland, they eventually determined to establish a new settlement in the New World and arranged with investors to fund them. They established Plymouth Colony in 1620, where they erect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squanto
Tisquantum (; 1585 (±10 years?) – late November 1622 O.S.), more commonly known as Squanto Sam (), was a member of the Patuxet tribe best known for being an early liaison between the Native American population in Southern New England and the ''Mayflower'' Pilgrims who made their settlement at the site of Tisquantum's former summer village. The Patuxet tribe had lived on the western coast of Cape Cod Bay, but they were wiped out by an epidemic infection, likely brought by previous European explorers. Tisquantum was kidnapped by English explorer Thomas Hunt who trafficked him to Spain, where he sold him in the city of Málaga. He was among a number of captives ransomed by local monks who focused on their education and evangelization. Tisquantum eventually traveled to England, where he may have met Pocahontas, a Native American from Virginia, in 1616–1617. He then returned to America in 1619 to his native village, only to find that his tribe had been wiped out by an epi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dolphin
A dolphin is an aquatic mammal within the infraorder Cetacea. Dolphin species belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named as dolphins. Dolphins range in size from the and Maui's dolphin to the and orca. Various species of dolphins exhibit sexual dimorphism where the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can briefly travel at speeds of per hour or leap about . Dolphins use their conical teeth to capture fast-moving prey. They have well-developed hearing which is adapted for both air and water. It is so well developed that some can survive even if they are blind. Some species are well adapted for diving to great depths. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fin Whale
The fin whale (''Balaenoptera physalus''), also known as finback whale or common rorqual and formerly known as herring whale or razorback whale, is a cetacean belonging to the parvorder of baleen whales. It is the second-longest species of cetacean on Earth after the blue whale. The largest reportedly grow to long with a maximum confirmed length of , a maximum recorded weight of nearly , and a maximum estimated weight of around . American naturalist Roy Chapman Andrews called the fin whale "the greyhound of the sea ... for its beautiful, slender body is built like a racing yacht and the animal can surpass the speed of the fastest ocean steamship." The fin whale's body is long and slender, coloured brownish-grey with a paler underside. At least two recognized subspecies exist, in the North Atlantic and the Southern Hemisphere. It is found in all the major oceans, from polar to tropical waters. It is absent only from waters close to the pack ice at the poles and relative ...

Cetacean
Cetacea (; , ) is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver. While the majority of cetaceans live in marine environments, a small number exclusively reside in brackish water or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species inhabit vast ranges where they migrate with the changing of the seasons. Cetaceans are famous for their high intelligence and complex social behaviour as well as for the enormous size of some of the group's members, such as the blue whale which reaches a maximum confirmed length of 29.9 meters (98 feet) and a weight of 173 tonnes (190 short t ...
