Intensive aquaculture systems, particularly recirculating systems, utilize equipment such as aerators, air and
water pumps, blowers, and filtration systems that inadvertently increase noise levels in fish culture tanks.
Sound levels and frequencies measured within intensive aquaculture systems are within the range of fish
hearing, but species-specific effects of aquaculture production noise are not well defined. Field and laboratory
studies have shown that fish behavior and physiology can be negatively impacted by intense sound. Therefore,
chronic exposure to aquaculture production noise could cause increased stress, reduced growth rates and feed
conversion efficiency, and decreased survival
