What's more, global warming, dams and pollution have taken a heavy toll on eel populations in North America and Europe.

The Japanese eel population, along with anguillid eel populations worldwide, have declined drastically in recent years.

Surveys by the Environment Agency show that the Gowy's eel population has held up well despite a Europe-wide massive decline in numbers.

Additionally, eel populations are dependant upon resource abundance, making their survivorship partially ecological.

It is home to lots of water birds and a large eel population.

There are strong concerns that the European eel population might be devastated by a new threat: Anguillicola crassus, a foreign parasitic nematode.

In Europe, eel populations are already from 30% to 100% infected with the nematode.

Fishermen consumed elvers as a cheap dish, but environmental changes have reduced eel populations.

I see that Parliament has taken very seriously the grave threat to the European eel population.

If we could reduce the number of elvers being taken, then we would build up the eel population.
