How common is the European eel in English rivers?
The European eel was caught in 29,365 of 66,062 surveys (44%) at 8,812 sites in England, 1975 to 2026.

What is the European eel?
The European eel (Anguilla anguilla) is a species of eel. Their life history was a mystery for thousands of years, and mating in the wild has not yet been observed. The five stages of their development were originally thought to be different species. They are critically endangered due to hydroelectric dams, overfishing by fisheries on coasts for human consumption, and parasites.
