| Description
| - Prostorová distribuce ryb byla studována v korytovité údolní nádrži Římov. Ryby byly loveny ve volné vodě na několika místech lokalizovaných podél podélné osy nádrže. K lovu byla použita standardní sada nordických průzkumových tenat. Výzkum probíhal v létech 1999–2003. Celková relativní denzita a biomasa ryb (úlovek na jednotku úsilí) klesaly od přítokové oblasti nádrže směrem k hrázi. Plotice (Rutilus rutilus), cejn (Abramis brama) a ouklej (Alburnus alburnus) tvořily dominantní část úlovku na všech místech nádrže. Zvýšená dominance cejna byla zjištěna v horní, nejvíce eutrofní části nádrže. Největší počet rybích druhů a největší úlovky 0+ ryb byly zaznamenány v přítokové oblasti nádrže. Úlovky do tenat podél vertikálních hloubkových profilů v jezerní části nádrže prokázaly, že ryby obývají především epilimnetickou vrstvu. (cs)
- The spatial distribution of fish was studied in the canyon-shaped Římov Reservoir (CZ). Fish were sampled by Nordic survey gill nets at several offshore areas along the longitudinal reservoir axis. Surveys were done in summer 1999-2003. The total relative fish abundance and biomass (catch per unit effort) decreased considerably from the upstream end of the reservoir toward the dam. Roach (Rutilus rutilus), bleak (Alburnus alburnus) and bream (Abramis brama) comprised the bulk of catches at all areas. Enhanced dominance of bream was observed in the fish assemblage at the uppermost, more eutrophic area of the reservoir. The highest number of fish species and the highest abundance of 0+ fish were found in the tributary area. In the downstream part of the reservoir, gill net surveys along the vertical depth profiles indicated that offshore fish occupied mostly the epilimnion.
