Abstract
A towed hydroacoustic system that provides rapid and precise estimates of pelagic (mid-water) fish stock abundance has been developed at the University of Washington. The system is self-contained, and therefore suitable for use on "ships of opportunity." It has been used to assess pelagic fish as part of the Coastal Upwelling Ecosystems Analysis program sponsored by the National Science Foundation.
