Story: Eels

Elvers, Karapiro spillway

Elvers, Karapiro spillway

Once glass eels enter fresh water they become darker, and are known as elvers. They swim upriver to find a home in a river, stream, lake or pond. Waterfalls and rapids are no barrier – elvers have a remarkable climbing ability and can even ascend the walls of some hydroelectric dams. In many places ‘eel passes’ have been built to help them get through.
