AB Biotic samples from Algeciras Bay (South-west Europe) were studied to assess its ecologicalstatus, complementing the previous abiotic monitoring of trace metals in water and sediments. Thisbay is a densely populated area with intense port traffic and is highly industrialised with metal inputs.To study the impact of this, Zn, Cd, Pb, and Cu contents were determined in tissues of benthic (Soleasenegalensis) and benthopelagic species (Scorpaena porcus, Trigloporus lastoviza, and Diplodus sargussargus). Notable levels of Zn and Cu were found in the liver and gills of all fish species. Comparedto international muscle guidelines, Pb sometimes exceeded the most restrictive values, outstandingS. porcus with 27% of samples above the permissible value. Metal pollution indexes revealed that theliver and gills of benthic species were more affected by metal pollution than benthopelagic species,especially in most industrialised sites. Particularly, S. senegalensis presented a higher accumulationfactor from sediment of Cd and Cu in the liver (30.1 and 345.1), probably due to the close interactionas benthic species. Among the species studied, S. senegalensis and D. sargus sargus proved to be thebest representative and useful bioindicators of metal-polluted environments as this bay. The resultswere consistent with the findings from the abiotic samples.
