The Czech multimetric fish based index (CZ-FBI) was developed recently. The aim of CZ-FBI is to assess the ecological potential of heavily modified and artificial water bodies and to detect ecosystems, particularly their specific components, in unsatisfactory conditions. This article describes steps of CZ-FBI development. Since the philosophy used, particular events presenting the results, to recent stage. CZ-FBI is a part of certified methodology of the Ministry of the Environment of the Czech Republic and the comparison with other assessment methodologies within a geographical intercalibration group is in process.

SPATIAL DISTRIBUTION OF FISH IN LAKE TURKANA, KENYA
MUŠKA, Milan
The knowledge of fish spatial distribution is essential for fish stock assessments and management. The aim of this study was to describe the fish spatial distribution in the vertical and horizontal point of view, estimate parameters of pelagic fish assemblage and compare this results with historical data.

Spatial distribution of fish in reservoirs and lakes
MUŠKA, Milan
This thesis is focused on the fish spatial distribution and its changes mainly during the diel cycle. In the first part, I described the fish spatial distribution in the tropical lake ecosystem of Lake Turkana. The second part deals with the fish spatial distribution in a temperate reservoir on the different spatial scales from in/offshore habitats over the fine-scale to the level of individuals. The linkage of fish distribution patterns with selected environmental variables was also evaluated.
