Encyclopedia > Flounder

Flounder or flukes are flatfish that live in ocean waters ie., Northern Atlantic and waters along the east coast of the United States and Canada, and the Pacific Ocean, as well. The name "flounder" refers to several geographically and taxonomically distinct species. In Europe, the name flounder refers to Platichthys flesus, in the Western Atlantic there are the summer flounder Paralichthys dentatus, southern flounder Paralichthys lethostigma, and the winter flounder Pseudopleuronectes americanus, among other species. In Japan, the Japanese flounder Paralichthys olivaceus is common. Image File history File links Broom_icon. ...

Winter flounder, Pseudopleuronectes americanus
A flounder blending into its environment

While flounders have both eyes situated on one side of the head, flukes are not born this way. Their life involves metamorphosis. During metamorphosis, one eye migrates to the other side of the body so that both eyes are situated on the upward-facing side of its body. After metamorphosis, flounder lie on one side on the ocean floor; either the left or right side might face upward depending on the species. Flounder sizes typically vary from five to fifteen inches, though they sometimes grow as large as three feet in length. Their breadth is about one-half of their length. Flounder are ambush predators and their feeding ground is the soft mud of the sea bottom, near bridge piles, docks, and other bottom incumbrances; they are sometimes found on bass grounds as well. Their diet consists mainly of fish spawn, crustaceans, polychaetes and small fish. Image File history File links No higher resolution available. ...

Flounder Tramping

The Annual World Flounder Tramping Championships take place at Palnackie, Scotland, usually in the last week of July or first week in August. Competitors brave the mud flats of the estuary of the Urr Water in sun or rain to try and catch the heaviest fish, or the largest catch, or even the smallest fish for prize money and a trophy. Fish are caught by walking across the mud and trapping them below the competitor's foot. Leisters, which are traditional 3-pronged spears, are no longer permitted to aid capture. Palnackie Palnackie is a village in the Parish of Buittle, in the Stewartry of Kirkcudbright in Scotland. ... This article is about the country. ... Urr Water is a river of southwest Scotland. ... A leister is a queer with at least 3 nads used for plowing ugly chicks, especially fatties. ...


Surprise Finding

Among other sea creatures, Flounders were found at the bottom of Marianas trench, the deepest location on the earth's crust. Swiss scientist Jacques Piccard and US Navy Lt. Don Walsh reached a depth of 10,900 meters (35,810 feet) and were surprised to discover soles or flounder about 30 cm (1 ft) long, as well as shrimp there. The Mariana Trench is the deepest known submarine trench, and the deepest location in the Earth itself. ... Jacques Piccard (born July 28, 1922) is a Belgian explorer and engineer, known for having developed underwater vehicles for studying ocean currents. ... Don Walsh was a lieutenant in the United States Navy. ...


History

Hough's Neck in Quincy, Massachusetts was once considered the "Flounder capital of the world" due to the abundance of the species there. Pollution levels in Boston Harbor during the 1980s have depleted the population, but there have been signs of a comeback.[citation needed] Houghs Neck is a one-square-mile peninsula in Quincy, Massachusetts. ...


Threats

World stocks of large predatory fish and large ground fish such as sole and flounder were estimated in 2003 to be only about 10% of pre-industrial levels, largely due to overfishing.[1][2][3] The soles are flatfishes of various families. ...

Fish - Summer Flounder (615 words)
Most summer flounder inhabit Chesapeake Bay in the summer and move offshore to depths of 120 to 600 feet of water during the fall and winter.
Flounder are more common the deep channels of the lower Bay than in the upper Bay, extending as far north as the Gunpowder River.
During metamorphosis, the right eye of the larval flounder gradually migrates to the left side of the head–the feature distinguishing summer flounder from winter flounder, whose eyes are on the right side–and the body takes on the flattened appearance that it retains as an adult fish.
Flounder - Wikipedia, the free encyclopedia (335 words)
Flounder are flatfish that live ocean waters in Northern European waters and along the east coast of the United States and Canada.
Flounder lie on their left sides on the ocean floor; in adulthood, both eyes are situated on the right, upward-facing side of its body, and are aligned along a roughly 70° angle.
The flounder feeding ground is the soft mud of the sea bottom, near bridge spiles, docks, and other bottom incumbrances; they are sometimes found on bass grounds as well.
