Biodiversity of fish in selected inflows of water reservoir Lipno 1
SALON, František
Monitoring of fish populations was performed in the localities having normal natural pattern with minimum ratio of and violation by anthropogenic activity. Monitoring took place in 2009-2010 in two localities, the Pestřice Brook and the Hamerský Brook. Electrofishing was used for the actual mapping of fish populations and selected flows. Fishing took place upstream, within the whole width of the stream and the length of the section reached approximately 100 m. Caught fish and lamprey species were determined, their length was identified by means of a measurement board and, after documentation, they were carefully returned back to the stream. The assessed data provide basic information about the species structure of fish population and its nature, development of diversity and equitability, species abundance, dominance and size variability etc. The mostly fished species Salmo trutta m. fario, Perca fluviatilis and protected and threatened species Lampetra plameri, Cottus gobio, Lota lota, Phoxinus phoxinus.
