Abstract: [cze] [eng]
Na pěti kaňonovitých nádržích v České republice byla studována distribuce plůdku ryb na podélných a hloubkových profilech těchto nádrží. Na dvou kaňonovitých a jedné mělké nestratifikované nádrži byla zkoumána účinnost plůdkových tralů v pozdním létě a na jedné kaňonovité nádrži byla zkoumána účinnost ichtyoplanktonních tralů na jaře pro larvy a časné juvenily. Patterns in 0+ fish distribution along longitudinal and depth profiles were studied in five canyon-shaped reservoirs in the Czech Republic. In two canyon-shaped and one shallow well-mixed reservoirs the efficiency of fry trawls was investigated during late summer for juveniles and in one canyon-shaped reservoir the efficiency of ichthyoplankton trawls was investigated during spring for larvae and early juveniles.
