It usually preys on wild fish that are attracted to farms, but also on farmed fish by biting holes in sea cages net walls. In the current telemetry study, we found that the tagged bluefish stayed close to fish farms during spring and early summer. However, most of the tagged fish disappeared from the farms during autumn, when the sea water temperature dropped. When aggregating at farms, bluefish were present at deeper waters during day time, but moved closer to the surface during night time. In addition, periods when there was operational activity at the farms might influence on daily swimming depth of bluefish. Therefore, bluefish individuals seem to find an optimal foraging habitat around Mediterranean fish farms.
