  5. Target strength of mackerel icefish (Champsocephalus gunnari) from a scattering model

    backscattered target strength (TS) of six mackerel icefish (Champsocephalus gunnari) of total length 26.8–35.0 ... cm, at 38 kHz. The model used computed tomography (CT) scans of fish to determine the sound speed and ... density throughout the fish and simulated the complex interaction of the incident sound wave with the ... applicable to fish of length 26–35 cm. Existing in situ TS estimates are for smaller fish (16–26 cm) and ...
