Description
In our project, we focused on the biodiversity of aquatic ecosystems. Project is related to the research project entitled: „The development of the methodology for the incubation of the selected salmon species and the innovation of the fish egg incubation boxes “(TJ02000229), funded by the Technology Agency of Czech Republic. This project was finished in the May 2021 and the main outputs was the methodology, which is unique in the ability to support and to restore the reofil fish population directly in the natural river habitat and to assess the potential risks for selected species caused by the impact of climate and land use change. The receiving of funding for this project will lead to further innovation of the methodology to another species such as Common barbel, Vimba vimba, Common nase, Ide and lampreys. The project is propose for 26 months (1.3.2022 – 30.4.2024) and there are four institution involved in the delivery project outputs, which will help to share good practice to the Norway and Great Britain. The incubation will be held in ten selected localities in the Czech Republic and will be actively supported by local fish communities, non-governmental organizations and nature protection authorities.
Summary of project results
In this project we follow up the previous research project entitled: „The development of the methodology for the incubation of the selected salmon species and the innovation of the fish egg incubation boxes “(TJ02000229), funded by the Technology Agency of Czech Republic. This project was finished in the May 2021. Our main output in the previous project was the methodology, which is unique in the ability to support and to restore the reofil fish population directly in the natural river habitat. With the help of Norway grants we were able to innovate the former methodology to another species such as Common barbell, Vimba vimba, Common nase, Ide and lampreys and spread the methodology among other subject active in fish protection.
During the project implementation we assess the potential risks (water velocity, water temperature, water depth). We assessed the risk for the present situation in the rivers and for the changes caused by the climate and land use change. We did the sssessment and the innovation of the methodology for ten localities in Czechia. It was the watercourses: Lomná, Opava, Morava, Losinka, Desná, Malé Labe, Smědá, Kamenice, Radotínsky potok a Polečnice. We geodetically surveyed 500m long river reach and applied the rainfall-runoff and hydraulic modelling afterwards. The results were maps for the present and future climate and land use change. There was an incubation of fish eggs for selected fish species and lamprey and sharing of know-how.
The important part of the project was spreading the good practice of incubation not only in Czechia (For Fishing expo, Workshop for stakeholders in the Jetřichovická Bělá stream), but also in Norway and United Kingdom. The incubation itself was carrying on with the active cooperation of the local fish communities, non-governmental organizations and nature protection authorities. Non-planned project output was the cooperation with the Norwegian University of Science and Technology and Norwegian Institute for Nature Research during the business trip. The project have crucial consequances from the perspective of positive influence of population of fish and lmapreys.
Several activities in the project will be continued. We calculated with the sustainability and one of the goal was to share methodlogy among the angler union. In near future, there will be incubation in area of Prague municipality with the support of the Anglers Union. Incubation of eggs of European grayling is planned in 2025 with the support of the Czech Anglers Union Šumoper and with others organizations with gain information about the methodology and are happy to apply it. The most crucial is the incubation of eggs of salmo salar in Bohemian-Switzerland National Park. This aktivity will be realized in following years under the leadership of Park management organization.
Summary of bilateral results
Cooperation with the Norwegian partner help us to understand the impact of climate change to watercourses in Norway and to the salmonidae species living in these environments. The results of the cooperation was Report, where the most recent knowledge about the potential threats to salmonidaes species in Norway are summarized as well as the impact of climate change to this population. As the Norway ia on of the leading country in the research of salmonidae species, information in the Report are valuable for the only one river with the population of salmo salar in Chechia – Kamenice river. With the help of the Norwegian partner, we were able to established cooperation with the Norwegian University of Science and Technology and the Norwegian Institute for Nature Research (during the work journey).
