Kanciruk, P. and C. H. Penington (1985). Hydroacoustic fishery assessment techniques: A feasibility study on the Mississippi River. U.S. Army Corps of Engineers Waterways Experimental Station, Technical Report WES/TR/E-85-10.
This study was initiated to evaluate the usefulness of hydroacoustic techniques in large, alluvial river systems. The hydroacoustic equipment evaluated operated at a frequency of 420 kHz and included down- and side-facing transducers, dual- beam echo integrators, and digital recording equipment operated in mobile and stationary surveys. It was found to be reliable, fairly easy to use (with adequate training), and provided information of fish abundance, distribution, and behavior patterns not easily attainable using conventional fishery assessment tools such as netting or electrofishing.
