Sampling of young-of-the-year fishes in rivers. New version
Jurajda, Pavel ; Slavík, O. ; Adámek, Zdeněk ; Janáč, Michal
Metodika je sestavena tak, aby bylo možné s jejím použitím provést odlov, základní zpracování a vyhodnocení vzorku plůdku ryb pro potřeby monitoringu ryb v tocích. Zvolená strategie odběru vzorků musí poskytovat informace o současném stavu rybího společenstva v dané lokalitě. V metodickém návrhu jsou obsaženy základní informace o cílové skupině ichtyofauny, výběru lokalit pro získávání vzorků, vlastním odběru vzorků, jejich zpracování a hodnocení.
Methodology of ecological status assessment of surface water bodies (category river) using fish fauna
Janáč, Michal ; Jurajda, Pavel ; Polášek, M. ; Němejcová, D.
Methodology specifies ecological quality assessment of river water bodies using BQE fish according to the Water Framework Directive (WFD, 2000/60/ECC) and national legislation requirements in this field. This methodology is fully useable in water management planning. Ecological status is classified into five classes on the base of comparison with reference conditions.
Management plan of small water supply reservoirs of Landštejn type
Halačka, Karel ; Adámek, Zdeněk ; Jurajda, Pavel ; Mareš, J. ; Kopp, R. ; Grmela, J.
The aim of the methodology is to provide managers and users of small water reservoirs Landštejn type with methodological tools for optimization of the water quality monitoring based on the current level of knowledge and research. Furthermore, provides a design of a methodology for fish community monitoring and optimization of treatments to reduce unwanted fish species and strengthen the status of suitable fish species with the aim of achieving the topdown effect and maintaining or improving water quality in these water reservoirs. The presented methodology summarizes the findings obtained during the monitoring and evaluation of selected parameters of water quality, planktonic and fish communities in water supply reservoirs Landštejn in recent years. It also contains an evaluation of applied treatments, focused mainly on fish stock. Unwanted fish species were caught and the predatory fish were stocked with the aim of optimizing the fish community composition and positively influencing the quality of the water in the reservoirs. The methodology contains recommendations for monitoring of the water quality in the reservoir, including monitoring of planktonic communities, monitoring of fish and recommended manipulation with fish stock. The methodology provides guidance and information for optimization of monitoring and treatments for small water supply reservoirs of the Landštejn type.
