Karpers in een viskwekerij groeien beter bij dagelijkse blootstelling aan muziek en licht.

Abstract:
The objective of this study was to further investigate the effects of music on fish physiology, bearing in mind available
information regarding the involvement of endogenous and exogenous factors in fish farming.
Therefore, Cyprinus carpio (50.5 +/- 0.36 g) were reared in a recirculating water system under 80 and 200 lux and subjected to no music at all (control, ambient noise only), 4 h of Mozart's "Eine Kleine Nachtmusik", or 4 h of anonymous "Romanza-Jeux Interdits" for 106 days.

Both music treatments resulted in increased growth performance at both light intensities, with Romanza treatment at 200 lux resulting in better growth performance than Mozart treatment.
Furthermore, feed efficiency for the Romanza groups was significantly better than for the control.

Although no significant music effect was apparent for brain neurotransmitters, lower anterior intestine alkaline protease levels were detected for both music treatments.
Taking into consideration the numerous advantages of recirculating water systems, it should be emphasised that fish response to music expresses the results of various physiological and biochemical processes, especially when fish notably respond differently when subjected to two different pieces of music.
