Celebrate: European week of the eel

You really wonder if they have nothing better to spend their money on in Brussels.

This week apparently is the week of the endangered species focusing on the eel.

There must be numerous people involved in this worthwhile project, but given the levels of unemployment in the Southern parts of Europe, you’d thought that would like to spend their money on something more productive.

But as we are great fans of smoked eel, and sympathise with endangered species, we’d thought we couldn’t withhold this vital bit of European information from you.

Species: European eel (Anguilla anguilla)

Status: Critically Endangered (CR)

Interesting Fact: It is thought that all European eels spawn in the Sargasso Sea after a migration of around 5000 km from European rivers.

European eels are catadromous fish, meaning they spend much of their lives in freshwater but migrate to the sea to breed. Transparent eggs hatch into larvae known as leptocephalli, which drift in the sea for up to three years. Pushed towards the European coast by ocean currents, they then undergo metamorphosis into young, transparent eels known as glass eels. Becoming darker, the young eels, now known as elvers, start to migrate up freshwater streams in large numbers. These eels remain in freshwater for up to 20 years, growing up to 1 metre long. Once sexually mature, the eels migrate back to the Sargasso Sea to spawn. Relatively little is known about the life history and migration routes of the European eels once at sea.

Eel populations have declined in recent years. The threats facing the species are not clear but it is thought that pollution, overfishing, habitat degradation, parasite infection and climate changes are all potential causes of the decline. Regulations are in place to protect these rare eels, including reducing fisheries, restocking, improving habitats and making rivers passable.
