A wide variety of hydroacoustic instruments from conventional standard models to state-of-the-art
models was equipped on the new training vessel Shinyo Maru (over all length 64.55 m, domestic gross
tonnage 986 tons) of Tokyo University of Marine Science and Technology. These instruments were
equipped for use in navigation, fishing, fisheries resources surveys, surveys for biological and physical
oceanography, seafloor and sub-bottom exploration, and their education. In this paper, the operating
principles and applications of these hydroacoustic instrument are explained. Particularly, in terms of the
hydroacoustic instruments used in the field of fisheries acoustics, this paper introduces their research
trends. Additionally, useful information on the installation of the hydroacoustic instruments for training
and research vessels are presented.
