Abstract
An aluminum towed body was designed for use in hydroacoustic surveying of fish stocks in shallow (2–10 m depth) inland waters. The design allows applications in deep (>10 m) water bodies as well. Test results showed that the towed body was a stable platform for the hydroacoustic transducer. The towed body features adjustable beam direction, allowing a side-looking as well as a vertical-looking mode. As the design of the towed body is simple, it can be easily constructed by any skilled craftsman.
