Exploitation of benthonic resources is an importantfraction within the craft catch. The main objective of this work was to obtain informationon the oxidative condition and tissue damage in gills of the limpets Nacella deaurata and N. magellanica with subtidal andintertidal natural habitats, respectively. No significant differences were observedbetween both species in the carbohydrates, lipids, proteins and ashes content. Ascorbylradical and lipid radical content was higher in N. deaurata compared to N.magellanica (224% and 3.5-fold respectively). However, catalase and superoxidedismutase activities were significantly higher in N. magellanica than in N.deaurata. hese data suggested hat in the intertidal species, which isexposed to extreme conditions, antioxidant activity is responsiblefor preventinglipid damage. Thus, organoleptic characteristics are improved, and conservationand handling stress could be prevented in intertidal compared to subtidalspecies. These studies would contribute to the sustainable management ofvaluable native species.
