Non-lethal sampling for the stable isotope analysis of the critically endangered European eel Anguilla anguilla: how fin and mucus compare to dorsal muscle - Dataset

Boardman, Rose, Pinder, Adrian, Gutmann Roberts, Catherine, Piper, Adam, Wright, Ros and Britton, Robert (2024) Non-lethal sampling for the stable isotope analysis of the critically endangered European eel Anguilla anguilla: how fin and mucus compare to dorsal muscle - Dataset.

The datasets for the manuscript "Non-lethal sampling for the stable isotope analysis of the critically endangered European eel Anguilla anguilla: how fin and mucus compare to dorsal muscle" are uploaded along with a readme file that explains the data column headings and information. Ecological studies on the critically endangered European eel Anguilla anguilla 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 δ13C and δ15N values of both eel fin and mucus are not significantly different from those of muscle and can be applied directly in comparative SI studies.
