| Outline of Final Research Achievements |
Floating aquaculture facilities are often used in culture fisheries and fish farming. In the case of rearing fish juveniles that have hiding behavior in the floating aquaculture preserves, the number of fish juveniles decreases due to the stress from movement of preserves caused by the waves.
In this study, we invented the wave energy absorption gadget operates on the principle that the natural frequency of the oscillating wave column is determined not by its volume but by its length.
We have conducted some field experiments in different conditions and acquired high wave energy absorption ratio besides better survival rate of fish juveniles in the floating rearing facilities.
