Management of commercial fisheries for Pacific salmon Oncorhynchus stocks returning to many of Alaska's (USA) large rivers has been hindered by the lack of timely information on stock strength and migratory timing. These rivers share characteristics (e.g., extensive multi-channel river mouths, turbid water, debris, large physical river dimensions, and presence of several fish species with overlapping spatial and temporal distributions) which make collection of such information difficult. Sonar was identified as a potential solution to the problem, and techniques of application and analysis were developed in the Yukon River between 1982 and 1985. Four primary components of the application are: identifying an appropriate site for equipment installation; identifying and ensonifying all areas of fish passage; expanding fish passage rates to temporal and spatial strata; and apportioning fish-passage estimates to species.
