抄録

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.
