| dc.description.abstract | The aim of my study was to verify if classical music really enhances the growth rate in Koi carp
as shown in the study performed by by VASANTHA et al. (2003). We also wanted to verify if,
classical music or music in general enhances growth rate of Koi carp, therefore I included a 3rd
group with chill out music to compare results.
A fourteen-week-long experiment was carried out to investigate whether music does influence
the growth rates of Koi Carp (Cyprinus carpio). Three tanks were set up with ten fish in each
tank; Tank A, Tank B, Tank C. Each tank was set up to have same water volume, water filtration,
light period, feed percentage intake and temperatures. Tank A contained chill out music – ‘Deep
House Mix’ by TREVOR NYGAARD, Tank B contained classical music – ‘Eine kleine Nachtmusik’
by WOLFGANG AMADEUS MOZART, while Tank C was used as a control and contained no music.
Weekly growth in weight, length and girth was measured and recorded and used to calculate the
weekly gain, the growth rate and specific growth rates of weight, length and girth. The difference
in growth between each group of fish was statistically tested for significance.
During the whole experiment the Mozart-fishes moved more, than the two other groups.
Results show, when comparing the first and the last week a significant difference (p < 0.05) in
specific length could be seen between Mozart and Control group. In specific girth measure,
significant differences could be seen between Chill-out and Mozart fishes and also between
Mozart and Control group. With respect to specific weight results, differences between Chill-out
and Mozart and between Mozart and Control group were noted. In all cases, the Mozart –fishes
were smaller and lighter, than the two other groups.
Chill-out fishes have the lowest fat percent in dry matter (82% that of the control), and
intermediary protein level (111% of the control). The highest protein concentration (119% of the
control) can be found in the body of the Mozart group, their fat level is also low (89% of the
control). | en |
