Reference: 1987, Vol 8, No 1, pp. 1-10.

Keywords: Acoustics, fish, length distribution, aquaculture

Abstract: This paper discusses the problem of size determination of fish without any handling requirements. Specially acoustical remote sensing based on resonance of the swimbladder is shown theoretically and experimentally.
