Fisheries Acoustics uses sound to detect, map, and count distributions of aquatic organisms. The use of acoustic technologies in the management of harvestable resources and ecosystem research continues to expand due to advances in electronics, alternate platforms, availability of off-the-shelf instruments, and the continued trend toward ecosystem management. Accurate conversion of acoustic data to estimates of animal size and population abundance or mass requires an understanding of the transmission of sound through water and the sound scattering properties of aquatic organisms.
This course introduces the use of sound as an aquatic sampling tool and applications of acoustics in resource management and aquatic research. The course will include lectures, assignments, laboratories, and an acoustic survey. Current echosounder hardware and software will be used to survey and count fish distributions in Lake Washington. Computer visualizations will be used to illustrate the aural reflective properties of fish.

Field Trip Insurance
Field Trip insurance is strongly recommended for all students registered in any SAFS course that includes field trips. Students who do not have the regular University insurance or adequate personal coverage should consider obtaining a special short-term policy at $0.85 per day for the course of the field trips. Information and applications are available on pages 27-29 at:
The completed application and payment (made out to the University of Washington) must be made to the Cashier's Office, 129 Schmitz Hall before the trip.
