“…For freshwater fishing, many of the studies cover managed systems where beneficial human activity includes stocking and sometimes feeding the fish (e.g. Boukal et al, 2012), but negative impacts also arise from over-fishing or habitat degradation, e.g. through pollution, dredging, deforestation or dam construction (e.g.…”

“…Most fishing grounds were located on mesotrophic and eutrophic streams and rivers. In addition, fish stocking is conducted annually on fishing grounds in the Czech Republic (Boukal et al., ; Humpl et al., ; Jankovský et al., ; Lyach & Čech, ); thus, most fishing grounds studied have high fish biomass (150–300 kg/ha). Fishing grounds located on oligotrophic rivers might show different patterns because catch and yield of anglers would be limited by low ecosystem productivity.…”

“…Recreational fishing in the Czech Republic is organised by the Czech Fishing Union and is centralised for the whole country (Boukal, Jankovsky, Kubecka & Heino, ; Humpl, Pivnička & Jankovský, ; Jankovský, Boukal, Pivnička & Kubečka, ; Lyach & Čech, ). The majority of fishing grounds in the Czech Republic is managed by the Czech Fishing Union.…”

This study aimed to assess the relationship between basic metrics in recreational fishing and the size of the fishing ground. Data were obtained from individual angling logbooks collected by the Czech Fishing Union over 12 years on 212 fishing grounds located in the regions of Prague and Central Bohemia in the Czech Republic. Small fishing grounds had the highest catch, yield, numbers of fishing visits and numbers of angling guard controls per hectare. Medium‐sized fishing grounds had the highest catch, yield, and numbers of both fishing visits and angling guard controls per fishing ground. Anglers returned to medium‐sized fishing grounds most frequently. The percentage of anglers who caught and took home at least one fish decreased with increasing size of the fishing ground. In conclusion, basic metrics in recreational fishing are related to the size of the fishing ground, which thus plays an important role in fisheries management.

“…The guild of phytophilous fish included species whose reproductive success depends on the presence of submerged vegetation such as crucian carp (Carassius carassius), rudd and tench (Tinca tinca). Northern pike (Esox lucius) and common carp, another typical phytophilous species, were not included because they are the most commercially important species for angling in the country and the populations in reservoirs are primarily driven by stocking (CFU, 2017;Boukal et al, 2012).…”

-The assessment of ecological quality in freshwater ecosystems is a key issue in many countries, but conditions for the development of assessment methodologies are often country-specific. This study proposes a simple methodology for the assessment of the ecological potential of reservoirs based on fish communities using a dataset covering major environmental and pressure gradients in reservoirs in the Czech Republic. Fish data obtained by gillnet sampling were correlated with a proxy of eutrophication as a key indicator of anthropogenic pressure for selecting appropriate fish-based indicators, establishing scoring criteria and developing the index of ecological quality. Expert judgement was also used to select potential fish indicators. Nine indicators were selected for the final fish-based index, fulfilling the criteria required by the Water Framework Directive. Two steps were used to validate the fish-based index quantification of its inter annual stability and sensitivity analysis of individual indicators. Finally, the index was compared to a previously developed general index for Central and Western Europe. Our study demonstrates that a combination of expert judgement and strict validation methods can result in an informative assessment of the ecological conditions, which can help identify conservation and restoration priorities.
