Description
| - Complex fisheries survey of the Prášilské Lake was undertaken in August 1999. The sampling effort included vertical and horizontal echosounding, deplyoment of pelagic and benthic multimesh gillnets, day and night shore seining and towing of the ichtyoplankton nets in the open water of the lake. neither method revealed any traces of fish presence. Instead of fish, a massive presence of water bug (Corixidae) species of Glaenocorisa proponqua was recorded by both echosounding and ichtyoplankton nets. High density of corixids was recorded especially after sunset in the very surface layers. These predatory animals may be responsible for the defensive migrations of Daphnia observed earlier. Hydroacoustic observations revealed also a very fine sediment whose thickness can be well monitored acoustically.
