AB Considering the overexploitation of fishing on most of the world coasts, the ingestion of fish and shellfish will depend mostly on aquaculture production. Since intensive mariculture usually involves environmental impact, developing sustainable cultures is a priority. In this sense, salt marshes can provide ecosystem services and incorporate both conservation and extensive aquaculture activities. In the present study we compared gilthead seabream Sparus aurata Linnaeus, 1758 cultured in extensive and semi-intensive marsh ponds with wild conspecifics from surrounding coastal areas, using trophic characterization (diet analysis and stable isotopes) and trace metal accumulation. Stomach content analysis revealed different feeding habits among gilthead seabream from different origin. Although wild specimens had the most diverse diet, results of stable isotopes showed that extensive diet had the wider isotopic niche and revealed the highest similarities between wild and extensively cultured gilthead seabream. A similar trace element signature was also measured in wild and extensive culture, whereas the semi-intensive culture showed different concentrations for several elements. Cr, Fe and Mn showed the highest concentrations in semi-intensive cultured fish, while As and Zn showed the lowest values in this group. In any case, average values measured in both extensive and semi-intensive culture were, in general terms, below the hazardous limits provided by the standards recommended for trace metals by national and international regulations. Therefore, marsh ponds provide a suitable environment where the cultured fish, especially extensive, should be promoted.

NO We are very grateful to all fishermen and producers of ‘esteros’ for providing fish specimens used for the study. Thanks are also due to Dr. P. Burgos for chemical analysis conducted in IRNAS-CSIC (Instituto de Recursos Naturales y Agrobiología, Consejo Superior de Investigaciones Científicas, Sevilla), Dr. Susana Carrasco for assistance during analyses of stable isotopes in the EBD-CSIC (Estaci´ on Biol´ ogica de Do˜ nana) and Drs. J. Moreira and J.A.Cuesta for valuable help with identification of diet items. We thank to two anonymous reviewers for valuable comments to improve the manuscript. Financial support for this study was provided by the Ministerio de Ciencia, Innovaci´ on y Universidades co- financed by the Agencia Estatal de Investigaci´ on -AEI- and Fondo Europeo de Desarrollo Regional - FEDER. During the study, ID-A enjoyed a grant ’Margarita Salas’ financed by the European Union (Next Generation EU) and the Ministerio de Universidades of Spain.
