Experimental setup used to test noise effects on common goby (Pomatoschistus microps) behaviour and reproductive success. The nest is in the middle of the aquaria with a male inside. A polypropylene tube, whit a lid in the bottom held in place by a net, in the right rear corner of the aquarium was filled with soft airgun balls. The airgun balls were bubbled with air in the noise treatments, either with a random intermittent or with a continuous temporal pattern. In the control treatment, the aeration of the airgun balls was always turned off.
