The swimming noise of a single fish and a fish school was studied. (1) Single fish: The sound was produced when a fish swam just below the surface of the water or jumped up from the water, but could not be detected when it swam under water. (2) Fish school: When the fish school was approaching the hydrophone in a pond, the sound was distinctly noticeable over the back ground noise. But in yellowtail crawl, it was not heard. In a pond or crawl, certain low frequency sounds were produced by sudden movements, jumping, and preying of the fish. (3) Skipjack fishing: When a skipjack was angled, the sound was observed, but it was not observed when they were approaching the prey. In operating the fishing boat, the noise was very loud, and the sound pressure produced by showering was very high.
