The swimbladder is considered to be responsible for most of the fish acoustic backscattering energy. An air-filled swimbladder can contribute up to 90% of backscattered sound. This paper discusses the results of in situ Target Strength (TS) measurement of Selar boops (Oxeye scad) and Megalaspis cord...
