Stable isotope analysis (SIA) was used to examine the isotopic relationships between dorsal muscle and fin, scale and epidermal mucus in pike Esox lucius . δ 13 C and δ 15 N varied predictably within each tissue pairing, with conversion factors calculated for the surrogate tissues, enabling their application to the non‐lethal sampling of E. lucius for SIA.
