Abstract

Sound scattering by a fairly sparse school of bladder fish is studied in a free medium, near an interface, and in a waveguide. The air bladder of a fish is approximated by a prolate spheroid with an axial ratio of 1:10. Characteristics of the back reflection of sound by a school of fish are calculated for various angles of irradiation, variable number of fish in the school, and various velocities of fish with respect to each other.
