Are American eels endangered? Should we care?

The American eel may be ugly, but if it disappears, the impacts on the ecosystem will be even uglier.
Anguilla rostrata聽is a catadromous fish, meaning that it migrates from freshwater to spawn in saltwater. The eels travel 1,600 miles from the Sargasso Sea to freshwater rivers and streams, and then back to the sea.聽
Unless, of course, they are intercepted by fishermen聽who sell them to Asian food markets, which pay top dollar for young "glass eels" that they聽raise to maturity.
Overfishing and habitat loss has caused the American eel population to decline sharply in recent years, prompting the聽US Fish and Wildlife Service to . A decision is expected this month.
鈥淭hey鈥檙e not pretty, cuddly, animals,鈥� says , marine and wildlife biologist, in an interview. 鈥淭hey鈥檒l never be the poster child of conservation, but that doesn鈥檛 mean we shouldn鈥檛 save them. The US is supporting the sale of tens of thousands of baby animals to Asia in this case and it's just not right.鈥�
鈥淓els are wonderful,鈥� says Simon Watt, president of Britain's , in an interview. 鈥淧artly because they are so mysterious.聽 We know so little about them even though they have been known to exist for hundreds of years. There for it imperative that we study them to understand just how threatened they might be. It聽belongs to the freshwater eel family, the Anguillidae and so聽is the only eel of its kind in the US.鈥�
Dr. Caleb McClennen, executive director for the Bronx Zoo鈥檚 Wildlife Conservation Society聽Marine Conservation Program, says in an interview that 鈥淚t鈥檚 a combination of pressures that have led to the decline with the top two being the significant loss of habitat and directed fishing of all life stages, particularly the larval or glass stage.鈥�
According to Dr. McClennen, 84 percent of the eels鈥� fresh water river habitat has disappeared. Maine and the Carolinas are responsible for fishing the glass stage eels, in particular.
Steven Shepard, a biologist with the US Fish and Wildlife Service, says in an interview that a consistent decline in the population plus habitat fragmentation by dams, fishing and other potential environmental factors have resulted in requesting the species be listed.聽
鈥淒ams fragment habitat and if they have hydroelectric they kill the eels. There are thousands of dams all along all these rivers in the Eastern United States. There鈥檚 a stressor that鈥檚 very widespread, very chronic鈥� says Mr. Shepard. 鈥淭he fisheries are also very widespread. In Maine, Chesapeake Bay and those have been reduced to address the decline in the population.鈥�
Should this status change pass, Shepard says that new restrictions 鈥渨ould have to be crafted to address the take. It could be as drastic as none at all or a very limited amount. That would have to be decided.鈥�
According to Mike Crowe, publisher of the commercial fishing newspaper , in Maine elvers are worth more than $2,100 per pound to buyers in Asia adding, 鈥淭hey鈥檙e plentiful in Maine because we鈥檝e taken care of our fresh water rivers and removed dams so the eels can get to their spawning grounds in the Sargasso Sea.鈥�
Darrell Young, co-director of the Maine Elver Fishermens Association, argues against a status change. 鈥淎dding severe limitations on the eels would impact this area in a big way," he says "It would put over a thousand fishermen out of work completely.鈥澛�
Mr. Galante adds, 鈥淧eople have to have an understanding of where food is coming from and where it鈥檚 going and think about the impact we have on it. At the end of the day, it鈥檚 all just part of a complicated, intricate food web and without that eel, the whole thing can crumble.鈥�
