Elvers: The Journey from Ocean to Estuary

What are Elvers?

As glass eels leave the open ocean to enter estuaries and ascend rivers, they are known as elvers. They are young eels that have recently undergone a metamorphosis from leptocephali, tiny, transparent larvae that drift in the ocean currents.

Elvers in North America

Elvers are fished at night from coastal rivers in Nova Scotia, New Brunswick, and Maine. They are a valuable commodity, and their catch is strictly regulated to ensure sustainable populations.

Elvers in Europe

In Europe, elvers are known as angulas. They are considered a delicacy and are highly prized in Spanish cuisine. The demand for angulas has led to overfishing and a decline in elver populations.

Conservation of Elvers

Elvers play an important role in the ecosystem, serving as food for larger fish and birds. It is essential to manage their populations sustainably to ensure their long-term survival.
