Cormorant Culling
Cormorant culling is the intentional killing of cormorants by humans for the purposes of wildlife management. It has been practiced for centuries, with supporters of culling generally arising from the angling community. Culling techniques may involve the killing of birds, the destruction of eggs, or both. Historically, culls have occurred to protect the interests of recreational and commercial fishermen who perceive the animals to be competing with them for their intended catch or for the prey of their intended catch. Since the 1960s, the growing aquaculture industry has undertaken cormorant culls to protect its farmed fish and crustacean stocks. Opponents of cormorant culling include conservation groups such as the National Audubon Society, Cormorant Defenders International and Sea Shepherd. Target species The target species are primarily the double-crested cormorant in North America and the great cormorant in Europe, Japan, and Australia. The little black cormorant has also be ...

Double-crested Cormorant (Phalacrocorax Auritus)
The double-crested cormorant (''Nannopterum auritum'') is a member of the cormorant family of water birds. It is found near rivers and lakes, and in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring in length, it is entirely black except for a bare patch of orange-yellow facial skin and some extra plumage that it exhibits in the breeding season, when it grows a double crest in which black feathers are mingled with white. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years. Taxonomy The double-crested cormorant was described by René Primevère Lesson in 1831. It was formerly classified in the genus ''Phalacrocorax'', but a 2014 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpshooters
A sharpshooter is one who is highly proficient at firing firearms or other projectile weapons accurately. Military units composed of sharpshooters were important factors in 19th-century combat. Along with "marksman" and "expert", "sharpshooter" is one of the three marksmanship badges awarded by the United States Army and the United States Marine Corps. The United States Navy and the United States Coast Guard use a ribbon with an attached "S" device to note a sharpshooter qualification. History Post-American Revolution (1794–1815) Some of the earliest mentions of rifling and sharpshooting units in the United States originate in the time following the American Revolutionary War and during the War of 1812. The US army abolished rifle units following the war in 1783, but they were later revived under General Anthony Wayne and used in the Battle of Fallen Timbers in 1794.Shock Troops of the Confederacy, Fred L. Ray The unit was again disbanded in 1796 following the conclusion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ayu Sweetfish
The ayu sweetfish (''Plecoglossus altivelis''), or sweetfish, is a species of fish. It is the only species in the genus ''Plecoglossus'' and family Plecoglossidae. It is a relative of the smelts and other fish in the order Osmeriformes. Native to East Asia, it is distributed in the northwestern Pacific Ocean along the coast of Hokkaidō in Japan southward to the Korean Peninsula, China, Hong Kong and northern Vietnam. It is amphidromous, moving between coastal marine waters and freshwater lakes and rivers. A few landlocked populations also exist in lakes in Japan such as Biwa. Original wild populations in Taiwan became extinct in 1968 due to pollution and present extent populations were reintroduced from Japan in the 1990s. The name "sweetfish" was inspired by the sweetness of its flesh. In reference to its typical one-year lifespan, it is also written as ("year-fish").

Phalacrocorax Carbo
The great cormorant (''Phalacrocorax carbo''), known as the black shag in New Zealand and formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (''phalakros'', "bald") and κόραξ (''korax'', "raven"), and ''carbo'' is Latin for "charcoal".

Taxonomy and etymology The long white-breasted cormorant ''P. c. lucidus'' found in sub-Saharan Africa, has a white neck and breast. It is often treated as a full species, ''Phalacrocorax lucidus'' (e.g. , ). In addition to the Australasian and African forms, ''Phalacrocorax carbo novaehollandiae'' and ''P. c. lucidus'' mentioned above, other geographically distinct subspecies are recognised, including ''P. c. sinensis'' (western Europ ...

Lake Ontario
Lake Ontario is one of the five Great Lakes of North America. It is bounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York. The Canada–United States border spans the centre of the lake. The Canadian cities of Toronto, Kingston, Mississauga, and Hamilton are located on the lake's northern and western shorelines, while the American city of Rochester is located on the south shore. In the Huron language, the name means "great lake". Its primary inlet is the Niagara River from Lake Erie. The last in the Great Lakes chain, Lake Ontario serves as the outlet to the Atlantic Ocean via the Saint Lawrence River, comprising the eastern end of the Saint Lawrence Seaway. The Moses-Saunders Power Dam regulates the water level of the lake. Geography Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7,340 sq mi, 18,960 km2), although it exceeds Lake Eri ...

Toadfish
Toadfish is the common name for a variety of species from several different families of fish, usually because of their toad-like appearance. "Dogfish" is a name for certain species along the gulf coast. Dolphin-Toadfish relationship Toadfish make up a notable portion of the dolphin's diet, approximately 13%. Scientific experiments have shown that the mating call of the toadfish alerts dolphin predators to the fish's location. Similarly, the sounds caused by the dolphin when hunting its prey alert toadfish to the location of the predators and cause the fish to silence their mating call. Male toadfish will reduce their mating calls by up to 50% when they hear the low sound of a dolphin's "pop". Batrachoididae The entire family ''Batrachoididae'' are called toadfishes. They are benthic ambush predators, known for their ability to produce sound with their swim bladders. Tetraodontidae The name "toadfish" is applied to some species of the family Tetraodontidae, including: * The ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
