  European eel - Wikipedia, the free encyclopedia
The slimy coating of the eel is thought to protect the fish against changes in salinity.
Since the 1970s, the numbers of eels reaching Europe is thought to have declined by around 90% (possibly even 98%).
Eels have been important sources of food both as adults (including the infamous jellied eels of East London) and as elvers.

 Eel - Wikipedia, the free encyclopedia
Some eels dwell in deep water (in case of family Synaphobranchidae, this comes to a depth of 4,000 m), or are active swimmers (the family Nemichthyidae - to the depth of 500 m).
Freshwater eels (unagi) and marine eels (Conger eel, anago) are commonly used in Japanese cuisine.
Eels in jellied form are a delicacy associated with East London.

His proposal was to release 50 Silver Eels from Danish waters with probes that will detach from the eels each second day, float up and broadcast position, depth and temperature to satellite receivers, possibly jointly with an equivalent release experiment from the countries of the western coast of the Atlantic.
European demand for eels could not be met for the first time ever, and dealers from Asia bought all they could grab.
In Europe, eel populations are infected already from 30% to 100% with the nematode.

 Eel - MSN Encarta
These eels, which are the most important as food and are often sold live in markets, have dense capillary systems close to the skin that can absorb oxygen directly from air or water.
When the very similar European eel and the American eel reach maturity in freshwater lakes and rivers, they take watercourses, sometimes slithering overland through dewy grass, to reach the ocean, where they swim or drift with currents for as long as a year until they reach the sluggish, weed-filled Sargasso.
The conger eel is classified as Conger conger, the European eel is classified as Anguilla anguilla, and the American eel is classified as Anguilla rostrata.

 Traffic Bulletin: Vol. 19, No. 2 (November 2002)
Eels are teleost fish (fish with bony skeletons) belonging to the superorder Elopomorpha and the family Anguillidae (Nelson, 1994).
It is known that the European Eel (and the American Eel) spawns in the Sargasso Sea in the western Atlantic Ocean, and the Japanese Eel, off the Mariana Islands in the western Pacific Ocean, and that the newly hatched larvae (leptocephali) are carried inland on currents (Figure 3) (Tsukamoto, 1992).
Eels are targeted at the stage they have reached in their life cycle when they pass through coastal waters, estuaries and rivers: glass eels are caught in southwest Europe and northwest Africa, yellow eels throughout the distribution area.

 Eel
The eel, however, has a pointed snout, like the conger, a large mouth gaping back as far as the middle of the eye or past it; and its gill slits are set vertically on the sides of the neck, their upper corners abreast of the center of the base of the pectoral fin.
Eels (European) are among the most prolific fish, ordinary females averaging 5 to 10 million eggs and the largest ones certainly 15 to 20 million.
Examples of long journeys by eels upstream, in New England rivers, are to the Connecticut Lakes, New Hampshire, at the head of the Connecticut River; to the Rangeley Lakes at the head of the Androscoggin, and to Matagamon Lake, at the head of the East Branch of the Penobscot.

 Anguillidae
The European eel migrates from the sea to freshwater during its larval and juvenile stages.
Eels are found in marine coastal waters, brackish waters (estuaries, lagoons, mangroves), and inland waters (rivers, streams, lakes, and marshes).
Once in brackish lagoons or in freshwater the young eels, which are yellowish to greenish brown become increasingly sedentary and territorial, adopting a large solitary existence, marked by a high rate of feeding on a wide range of animal species.

 Growfish - Gippsland Aquaculture Industry Network (GAIN)
The European eel, a snakelike fish with a mysterious life cycle, has managed to survive in rivers and on farms despite overfishing and a loss of natural habitat, thanks to artificial restocking with "glass eel" - tiny eel fry.
For the 25,000 eel fishers and countless animals that live off the eels, the future is uncertain.
Eel live in fresh water for 15 to 20 years, then, turning from yellowish green to silver, swim far out into the Atlantic Ocean and are believed to spawn somewhere in the vast kelp bed of the Sargasso Sea.

 Eel Farming in Taiwan
Eel farming is at the top of the fishery industry in terms of export value.
Eel culture in Taiwan can be in the form of a nursery operation, raising newly transformed elvers of Anguilla japonica to fingerlings, in the form of a production operation, raising fingerlings to market size eels, or a combination of the two.
Because eels are a mild animal and their reproduction occurs only in the sea, they will not threaten the existence of other species in the same habitat provided that the farm eels escape into the wild.

 TRAFFIC Dispatches Number 16 March 2001
Also, dams that limit the migration of eels (in "silver eel" stage) back to the sea, and possibly the subsequent reproduction and survival of early larvae together with over-fishing at local rivers and estuaries are thought to contribute to the decline.
Eels are mostly caught young in Western Europe and then exported to Asian eel farms in China, South Korea and Japan and then sold and consumed mainly in Japan.
Recently, the commercial aspects of eel fisheries have also been highlighted in discussions between the FAO Working Group on European Eel of the European Inland Fisheries Advisory Committee (EIFAC) and the International Council for the Exploration of the Sea (ICES) and it is anticipated that further discussions about these issues will follow.

Eel live in fresh water for 15 to 20 years, then head for the ocean when they are ready to breed, changing from a yellowish green to a silver color as they go.
Because the American eel population is also in decline, some scientists believe the real problem may be changes in ocean currents due to global warming or a parasite or virus that has infected the breeding zone.
Glass eels are caught mostly on the shores of France, Spain, and Portugal, while the northern European industry is focused on adults.

No one knows exactly what the reasons are for the eel’s absence but there is certainly no lack of theories and attempts to explain the situation: Overfishing and water pollution are named just as often as river obstructions such as weirs and barriers or hydroelectric power stations whose turbines injure or even kill the eels.
The glass eel fishery in the river estuaries that mainly provides stock for the eel farms must be regulated so that there are still enough glass eels left to ascend into the rivers.
Restocking (eels are caught in one region and then released in other regions) has a long tradition in Europe, sometimes dating back as far as the 19th century.

Within the North Atlantic, ocean currents isolate a large elongated body of water known as the Sargasso Sea, in which the salinity is noticeably higher than average.

 American Eel Endangered List
As temperatures cool and eels make their way downriver in their migration to spawn in the ocean, they undergo physical changes to prepare their bodies for spawning and for the transition from freshwater to the marine environment.
According to recent European research, eels that are delayed, for example due to barriers or rises in temperature, and are unable to complete their downriver migration can actually reverse that physical change and regenerate their guts.
Bell remains interested in reviewing new scientific and commercial data on the eel’s status, threats that may affect the species, and life history characteristics important to understanding the impact of threats as she coordinates the status review.

Adding insult to injury, the eel is already vanishing from lakes and rivers across Europe, and some of these toxic chemicals look as if they might last longer than the species itself.
With populations in some European waters as low as 1 percent of historic levels, the eel clearly doesn't need a toxic burden.
But while eels might be slippery and tricky to control they have nothing on the worst excesses of the chemical industry.

In the last 20 years, European eel stocks have declined to just 1 percent of their former levels, and Asian eels to 10 percent.
For instance, although European eel larvae have been found in the Sargasso Sea south of Bermuda, no one knows where European eels spawn: Neither spawning fish nor eggs have ever been observed in the wild.
