Application of three sound scattering models to threadfin shad (Dorosoma petenense)

Three sound scattering models [T. K. Stanton, J. Acoust. Soc. Am. 86, 691–705 (1989), C. S. Clay, J. Acoust. Soc. Am. 89, 2168–2179 (1991), and C. S. Clay and J. Horne, J. Acoust. Soc. Am. 96, 1661–1668 (1994)] were used to model backscatter measurements from individual threadfin shad. Thirty three threadfin shad from Lake Norman, North Carolina were insonified at 120, 200, and 420 kHz to determine acoustic backscattering cross sections. The measurements covered the range of fish total length (TL) over acoustic wavelength (λ) of 4
