Title: AQUACULTURE DEVICE, AQUACULTURE SYSTEM AND AQUACULTURE METHOD
Abstract:
Provided are: an aquaculture device having a simple structure which uniformly irradiates ultrasonic waves, among acoustic waves, within a water tank so that the resistance of aquatic animals being cultured can be improved and the survival rate thereof can be elevated, thereby increasing the yield; an aquaculture system; and an aquaculture method. An aquatic animal 29 being cultured is irradiated with acoustic waves comprising sonic waves and/or ultrasonic waves. The aquaculture device comprises: an ultrasonic oscillator 20 capable of generating acoustic waves; a driving section 15 driving the ultrasonic oscillator 20; and an outer case 12 holding the ultrasonic oscillator 20 and the driving section 15. On the side of the front face toward which high-strength acoustic waves 19 are radiated from the ultrasonic oscillator 20, an acoustic wave-scattering layer 24, which is formed of an acoustic wave-scattering material and capable of scattering the high-strength acoustic waves 19 while converting the high-strength acoustic waves 19 into low-strength acoustic waves 21 having a lower strength per unit area and then irradiating the same, is provided.
