Variety of instruments are developed for surveys on fishery resource and oceanographics, for observation on behavioral ecology of marine organisms, and for monitoring actual fishing or aqua-culture. In addition, basic investigations are also performed on acoustic scattering properties or sense organs of marine organisms.
