Activists blend science and folklore as they try to revive Somerset’s eel population

Hugh Fearnley-Whittingstall and Feargal Sharkey back campaign to save the animal, which once inspired placenames, songs and stories

When the Somerset Levels flood in winter, their reed-fringed waterways swell into a glinting inland sea - haunting and half forgotten.

Generations ago, these wetlands pulsed with the seasonal arrival of eels: twisting through rhynes - human-made water channels - and ditches in their thousands, caught in baskets, sung about in pubs and paid as rent to Glastonbury Abbey. Today those same waters flow more slowly, more sparsely: once-teeming channels now show only the barest traces of what was here.
