Abstract:

The long-term goal of this program is to quantify, understand and predict acoustic backscatter from fish. Objectives of this project include quantifying the relative importance of biological and physical factors that influence variability in backscatter amplitudes comparing backscatter measures to predicted amplitudes from anatomically-based scattering models examining the application of sonar technologies to the enumeration and discrimination of acoustic targets and acoustically quantifying size distributions, abundances, and behaviors of fish.
