The distribution and structure of Common Minnow (Phoxinus phoxinus) populations in the Malše river basin
 LUKEŠ, Václav
This thesis was elaborated within the MSM 6007665801 research intention. The objective of the thesis was to create an overview of the distribution of Common Minnow in the basin of upper and middle reaches of the Malše River. Selected stretches of the Malše River, Černá River and Pohořský, Huťský, Tisový and Žďárský Brooks were monitored. These streams correspond to trout waters in their character. The field research was conducted in the years 2005?2008. Estimates of quantity and indexes of diversity and eguitability in the fish communities were calculated. Estimates of biomass in the population of Common Minnow were calculated and the length frequency distributions were determinated. Common Minnow was found in seven out of twenty examined stretches.
