Researchers at Newcastle University found that European sea bass experienced higher stress levels when exposed to the types of piling and drilling sounds made during the construction of offshore structures.The fish also showed signs of being confused when they encountered a potential predator while exposed to these underwater noises. When researchers played recordings of piling sounds and mimicked an approaching predator, the seabass made more turns and failed to move away from the predator.  When exposed to drilling sounds the sea bass actively avoided these areas, spending more time in what the research team called the ‘safe zone’.
