First report of a swordfish ( Xiphias gladius Linnaeus, 1758) beneath open-sea farming cages in the Western Mediterranean Sea

An adult individual of swordfish ( Xiphias gladius L.) was reported for the first time aggregated at coastal Mediterranean fish-farm facilities. This record highlights the necessity to assess the potential ecological changes on wild fish assemblages by coastal farming activity, especially on this type of endangered large migratory fish predators, which might be taken into account for further management strategies.
