Mozart Improves the Quality of Our Food

From a study by Papoutsoglou, S. E., Karakatsouli, N., Batzina, A., Papoutsoglou, E. S., and Tsopelakos, A.:

The aim of the present study was to evaluate music effects (Mozart, K525) on gilthead seabream Sparus aurata and investigate whether its response to music was differentiated when combined with different lighting conditions. Therefore, S. aurata (mean ±s.e. 1·51 ± 0·01 g) were reared in re-circulating water system under 80 and 200 lx and subjected to 2 and 4 h of music transmissions or to no music at all (control, ambient noise only). Underwater ambient noise of the equipment ( e.g. pumps and aerators) in all experimental tanks was 121 dB re 1 µPa and music transmitted was set at 140 dB re 1 µPa. During the first 89 days of rearing, music resulted in enhanced growth. Nevertheless, at the end of the experiment (on day 117) no significant differences were found for body mass but music treatment resulted in more homogeneous fish populations than controls. Brain neurotransmitter levels were reduced especially when music transmission was combined with 200 lx. Feed utilization was significantly improved when fish were subjected to 4 h of music and 200 lx, while stomach proteolytic enzymes and intestine total carbohydrases were lower and higher, respectively, compared to controls. Some differences were also observed in liver and plasma fatty acids composition. The present results provide the initial evidence that music transmission under specific rearing conditions could have enhancing effects on S. aurata growth performance, at least at specific fish sizes. Moreover, the observed music effects on several aspects of fish physiology ( e.g. digestive enzymes, fatty acid composition and brain neurotransmitters) imply that music could possibly provide even further enhancement in growth, quality, welfare and production.

Mozart K. 525:

We have already seen numerous studies posted here on the benefits of classical music not only to humans, but to fish, birds, dogs, and even plants. Let’s stop dithering around, and just admit that classical music improves the quality of life for ourselves, our plants, our pets, and yes, our food sources, and start taking action!
