Tuna, due to their position in the food web, serve as excellent biomonitors for assessing health of marine ecosystems. Analyzing organs and tissues provides valuable insight into element concentrations, tuna possess capacity bioaccumulate pollutants. In present study, 12 trace elements metals (Al, B, Cd, Co, Cr, Cu, Fe, Li, Mo, Ni, Pb, Zn) were analyzed dorsal fin spines samples four species: Katsuwonus pelamis, Thunnus albacares, obesus thynnus from individuals captured surrounding waters Canary Islands, between 1990 2007. To analyze data, descriptive statistics one-way two-way PERMANOVAs carried out, with species factor decade-species factors, respectively. The highest concentrations recorded elements: Al, B Zn, greater significant differences both decades, Pb Zn. comparison decades showed a decrease them, 90s 2000s. There is no similar information on metal content these species, providing relevant information, which may be interest future studies.
