Abstract

Fisheries Acoustics is a relatively young discipline in freshwater research and management, particularly in the developing world. While primarily employed in the marine environment, the methods have not yet been tested extensively and optimized to large, fast flowing, high turbulent riverine systems, where strong turbulence in highly structured, shallow habitats may cause yet unknown interference and where signal distortions need to be investigated to assure proper interpretation. Improvements in the application of hydroacoustics are particularly warranted for rare and highly endangered species. Certainly sturgeons are among these, and where they can actually serve as model species for all species where population densities are extremely low and at the same time where an individual fish may be very large. Monitoring their migration, temporal occurrence, aggregation on spawning grounds and residence time in various river stretches during the pre‐spawning period (after entering the rivers) is of utmost importance in order to gain basic insight into the actual spawning stock biomass of these species. Certainly, the use of hydroacoustics offers the simultaneous opportunity to monitor interactions between and among species and expand the studies to place sturgeons within a larger context. In this sense the Yangtze River studies are exemplary and can therefore be imbedded into investigations of the entire fish community in this large river system. The dual interests of sturgeon specialists and river fisheries institutions led to the workshop on this subject jointly organized by the Committee of Fishery Resource Conservation and Utilization, Chinese Academy of Fishery Sciences and the World Sturgeon Conservation Society, with support from the Yangtze River Research Institute . The workshop also represents the 4th Annual meeting of the Chinese Fisheries Acoustics Group. The workshop input was mainly local. However, several of the papers were selected for reasons of wider interest and are thus published in this journal. To reflect the overall subject coverage of the workshop, the other papers are presented as Extended Summaries. Furthermore, these papers will be published in full in a special publication of the World Sturgeon Conservation Society. Neu Wulmstorf (Germany) and Wuhan (China), October 2013.
