The Effect of Different Tempos of Music During Feeding, on Growth Performance, Chemical Body Composition, and Feed Utilization of Turbot (Psetta maeotica, Pallas 1814)

Abstract

The effects of different tempos of music on growth, body chemical composition and feeding parameters of turbot (Psetta maeotica, Pallas 1814) were investigated. Turbot (average weight 160.61 +/- 1.53 g) were reared in a circulating sea water system for 8 weeks with music playing for 5 hours at each feeding. The music treatments consisted of slow tempo music (adagio; metronome speed 66-76), medium tempo music (moderate; metronome speed 108-120), fast tempo music (allegro; metronome speed 120-168) and control group (no music). Results demonstated that the fast tempo music treatment (FTM, p<0.01) had a negative effect on fish growth, but when slow tempo music (STM) was transmitted, growth improved slightly. Best growth performance was observed when the fish were exposed to slow tempo music. The FTM group showed signs of stress and reduced feed intake. Music transmission significantly affected carcass fat content (p<0.05). No significant effect was observed on protein, ash or moisture content.
