Abstract.
Altogether 71 samples collected in 1968-2004 from the Rokytná and Loucka rivers were used to estimate proportional fish species richness from single-pass electro-fishing and probabilities of detection for individual fish species. Mean estimated species richness from single-pass sampling (p'^sub sl^) was 95.4% and 96.2% of estimated total species richness for Rokytná and Loucka rivers, respectively. However, p'^sub sl^ values for individual sites ranged from 71.4% to 100% of...

; INTRODUCTION Species richness, the number of biological species, is related to community productivity for a broad range of organisms found in different types of ecosystems (Grime 1973, Huston 1979, Begon et al. 1990, Rosenzweig and Abramsky 1993, Tilman 1993). Often, biological species richness
