Abstrakt:	Abstract: This study solves the problem of evaluating the quality of salmonid fisheries in the Czech Republic using catch and stocking statistics provided by the Czech and Moravian Anglers Unions for the years 2000-2010. The quality of 200 salmonid fisheries belonging to Czech Anglers Unions (Local Organization for North Moravia and Silesia, South Bohemian Board) and the Moravian Anglers Union was evaluated. Using factor analysis they were each placed in one of five categories (A-E). Fisheries with the highest catches and stocking of fish were evaluated as "TOP salmonid fisheries", classification A, which is based mainly on their indigenous ichthyofauna in terms of the significant species Salmo trutta m. fario Linnaeus, 1758 and Thymallus thymallus Linnaeus, 1758 (Salmonidae). There are only a small number of fisheries in the highest rated categories A and B, which make up 2% of all the fisheries. Most of the fisheries (68%) were placed in category D. Comparison of the quality of these organizations is very difficult as they are each regulated and managed differently.
