common to the natural habitat of the brown shrimp. Additionally,
Terhune et al. (1990) observed decreased growth and smoltification
rates of Atlantic salmon, Salmo salar, in fiberglass tanks that had
underwater sound levels 2–10 dB re 1 μPa higher at 100–500 Hz than
concrete tanks. Although the following study evaluated an artificial
sound stimulus that is uncharacteristic of aquaculture systems it is
important to mention that Papoutsoglou et al. (2007) observed
increased growth rates and lower levels of stress-related brain neurotransmitters
in common carp, Cyprinus carpio, when Mozart music
was transmitted to culture tanks under certain light conditions.
