摘要：

Mobile acoustic techniques (echo-sounding and echo-integration) for fish surveys were used in shallow waters of depths less than 5 m. These techniques show the importance of fish biomass in the side-channels and the detection of echoes in the main channel. Diurnal spatial migrations are seen. The advantages and limitations of the method as a complement to traditional sampling methods in the river are examined.
