<jats:title>Abstract</jats:title><jats:p>Ecological studies on the critically endangered European eel <jats:italic>Anguilla anguilla</jats:italic> often incorporate stable isotope analysis that typically uses dorsal muscle sampled from euthanised eels. To minimise the lethal sampling of imperilled populations, fin tissue and/or epidermal mucus can provide non‐lethal alternatives to muscle. The results here indicate that δ<jats:sup>13</jats:sup>C and δ<jats:sup>15</jats:sup>N values of both eel fin and mucus are not significantly different from those of muscle and can be applied directly in comparative SI studies.</jats:p>
