The isotopic offset (Δ Cand Δ N) between muscle and scales indicate that the application of scales instead of muscle allow to apply non -lethal methods on isotopic studies regarding fish species for conservation purposes. This technique has been proven to be appropriate for trophic studies of fishes at marine protected areas
