A critically endangered species

The European eel is listed as Critically Endangered on the IUCN Red List, as reported by FishBase. It is in CITES Appendix II, and the European Union adopted an eel recovery regulation (EC 1100/2007) requiring national eel management plans. This page is not about how to catch eels: it explains why they should not be targeted and what to do if one takes your bait.

An extraordinary life cycle

According to FishBase, eel spawning has never been observed; it is believed to take place only in the Sargasso Sea, probably between March and June. Transparent, leaf-shaped larvae drift to Europe on the Gulf Stream in 7-11 months, then turn into glass eels of 6-8 cm (2.4-3.1 in) that move up estuaries into rivers and lakes. A long growth phase follows as yellow eels, lasting 6-12 years for males and 9-20 years for females. As silver eels, they head back to sea on dark nights, mostly in the second half of the year, spawn once and die.

Every silver eel that fails to reach the sea is a lost spawner. The review by Jacoby and colleagues (2015) describes the combined threats: barriers and turbines, fishing, pollution, parasites and ocean change.

Sizes

Common length is 35 cm (13.8 in) for males and 50 cm (19.7 in) for females; the maximum published is 133 cm (52 in) and 6.6 kg (14.6 lb) (FishBase).

What the rules say

Rules are strict and change often. In England and Wales, anglers must currently return all eels they catch; in Ireland, eel fishing has been closed under the national eel management plan; other countries have seasons, bans on silver and glass eels, or catch-and-release only. Never rely on old information: check the regulation page for your area and the relevant authority before night fishing with worms. In North America, the American eel (Anguilla rostrata), a different species, has its own state and provincial rules.

If you catch one by accident

Eels sometimes take worms or deadbaits, especially on warm nights. Release them immediately. If the hook is swallowed, cut the line close to the mouth: trying to remove it does more harm. Litt and colleagues (2020) ran a hooking mortality experiment on the closely related American eel. Using larger hooks and striking early reduces deep hooking.

Lures and baits

  • None: do not target eels. If one is caught accidentally on worm or deadbait, release it immediately.

Catch and release

  • Release any accidentally caught eel immediately, where required and even where it is not.
  • If the hook is swallowed, cut the line close to the mouth rather than trying to remove it.
  • Handle with a wet cloth, gently and briefly.
  • Larger hooks and striking early at night reduce deep hooking.
