Fish and Wildlife Service announced September 28, following an initial review of a petition seeking to protect the species under the Endangered Species Act (ESA). The American Eel population has declined by more than 99 per cent in Ontario. The status was re-examined by COSEWICin May 2012 and designated Threatened. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. While American eels still face local mortality from harvest and hydroelectric facilities, this is not threatening the overall species. The American Eel In April 2006, the Committee on the Status of Endangered Wildlife in Canada designated the American eel as Special Concern (Reassessment planned for April 2012).

In this first assessment of the American eel, the IUCN saw a troubling trend: a drop of around 50 percent in the population in the past several decades. Maine is one of two states that allow glass eel harvesting, and until last season it had no quota for the fishery. Catadromous fish are born in saltwater, then migrate into freshwater as juveniles where they grow into adults before migrating back into the ocean to spawn. He suggested to first evaluate the IUCN’s listing as a hypothesis, one which warranted an evaluation, rather than accept it as a final assessment. Ontario's Ministry of Natural … It begins in the ocean, in the Sargasso Sea, where all eels spawn. The American Eel was assessed as Special Concern by COSEWIC in April 2006.

Now, fisheries managers are looking to the Delaware, the longest undammed river east of the Mississippi, as a model for bringing back this uncharismatic, but vital, fish. When the eel larva hatches from the egg, it is carried in the Gulf Stream for up to a year. And is the only catadromous species found in North America as well.

The life cycle of American Eel involves several stages. But conservation efforts will need to be extraordinary to bring the eel population back to health. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, Forever Chemicals Are Widespread in U.S. Shelf: The effect of climate change on American Eel is estimated to be neutral, but this estimate has uncertainty (66-90% certainty in expert scores). “That’s what makes the conservation piece so tricky.”, Climate change makes the picture even more complicated since it could alter ocean currents. A status review of the Atlantic coast American eel populations was completed in January 2007 and 2015. © 2021 Scientific American, a Division of Springer Nature America, Inc.

They are common in Eastern North America where they live in rivers, lakes and ponds, feeding on invertebrates, fish, insects and carrion. The decline, abetted by sky-high demand from Asian markets, placed the species in the IUCN’s endangered category. However, the ability for individual American Eel to shift distribution once in freshwater habitats is limited. The American eel is at very high risk of extinction in the wild, the International Union for Conservation of Nature (IUCN) announced last month. The American eel has only recently become a sought-after fish, since the 2011 tsunami in Japan wiped out eel stocks and Europe banned eel exports a year later. But the species is at risk. The American Eel (Anguilla rostrata) is a wonderfully peculiar fish with a snake-like body which can reach 4 feet in length.This species is catadromous, meaning they spend most of their lives in fresh water and migrate to the sea to breed.

Other Names: Common Eel, Freshwater Eel . Considering Endangered Species Act Protection. With Asian and European eel off the market, the American eel has became a sought-after alternative. This move means fishermen can harvest more eels if Maine reduces its river pollution or knocks down dams to open spawning habitat. Results of both of these reviews determined that Atlantic coast American eel populations did not warrant a listing as threatened or endangered. Origin: Native . “No one really knows how those threats combine to cause population declines,” Jacoby says. In 1900, American eels were prolific throughout the Susquehanna and Delaware rivers. Directional Effect in the Northeast U.S. A young life phase of American eels, called glass eels, cyclically fetch a high price on the Asian market and are also harvested in the United States.
