Sažetak
This study tests the suitability of the Gilthead seabream scales as a proxy of environmental and ecological changes in wild and anthropogenically pressured environments. Scale morphology and microchemistry were used to discriminate a habitat selection of 8 wild, 6 farmed and 2 wild farm- associated populations, where landmark and outline- based scale morphometrics, trace elements chemistry and scale microstructures characteristics were analysed. Applied scale morphometrics techniques were able to differentiate the farmed from wild origin scale phenotypes but with a reduced discrimination sensitivity between wild and wild farm-associated origin. However, microchemistry scale elements (B, Ba, Mg, Mn, K, Sr, Zn) were able to fully classify individuals according to their origin thus proving to be a more powerful tool in determination of the origin of gilthead seabream. Disparity in the scale microstructure characteristics accounted for the number of radii, circuli and intercirculus spacing pointing to the differentiation in the growth and environmental conditions between wild and farmed fish. In brief, scale shape was found to be primarily useful as an exploration tool for identification of farmed fish whereas scale microchemistry provided a good resolution in identifying gilthead seabream membership among different habitats. More research is needed in the process of evaluating performances of scales as a nonlethal biogeochemical tag taking into account the importance this species exercises in the sectors of aquaculture and fisheries throughout the Mediterranean.
