Summary of main results and their impact on freshwater pearl mussel

Within the frame of the project were realised identification, localisation and digitalisation of conflict between forest management plan for 2014 – 2024 and food resources of freshwater pearl mussel in the headwaters of the Blanice River. Thus, our results enable more effective protection of important food sources. Furthermore, bio indication results suggest that evaluated springs are non-toxic for freshwater pearl mussel juveniles and their detritus could be used as important food source for freshwater pearl mussel artificial reproduction according to methodology of APES. Besides that was verified the possibility of freshwater pearl mussel spread through its host in the Boletice Military Training Area and adjacent streams. In this context was as the management unit for freshwater pearl mussel defined the whole catchment of upper Blanice River. According to this was recommended to realize a complex protection of wild brown trout population through fisheries management restrictions with emphasis on natural reproduction and also migration barriers removal.

We would like to invite you on seminar of the Action Plan for Endangered Species for Freshwater pearl mussel (Margaritifera margaritifera) that will be held 29. 11. 2016 from 10:00 in the Czech Agricultural University campus. Please let us know in advance if you are interested to join the seminar.

In winter season will be conducted analyses of data gathered during summer months. „In situ“ tests will be one of the main issues, analysing tests that were conducted from May to August on twenty localities.

Freshwater pearl mussels were measured and inserted into plates that were deposited in observed streams. Control and maintenance were conducted during summer. Two plates were replaced due to the low water level. Plates were collected and freshwater pearl mussels were re-measured at the end of August.

These data are currently analysed.

In relation to spring mapping were selected springs laboratory assessed with “ex situ tests” according to methodology of APES and subsequently categorized into separate trophy categories. During the extensive field sampling were gathered detritus samples from 100 localities in the Boletice Military Training Area.

Freshwater pearl mussel juveniles were photographed before and after the experiment using the stereoscopic microscope in order to assess their growth. Currently are these data analysed.

Within the activity no. 1 spring mapping were from July of this year localised 426 places, from which were 278 spring streams.

During the project realization will be held two seminars in order to inform about the progress and preliminary result of the projects. The aim of the seminars is also to discuss topics related to the project realisation. Detailed information about seminars will be provided in advance.


Implementation of the Action Plan for Endangered Species for Freshwater pearl mussel

(Margaritifera margaritifera) in the Boletice Military Training Area

The project is financed by EHP funds 2009-2014 and by the Ministry of the Environment of the Czech

Republic. The aim of the project is implementation of action plan for freshwater pearl mussel

(Margaritifera margaritifera), namely mapping and research of its food resources and monitoring of

the brown trout populations in relation to reproductive possibilities of the fresh water pearl mussel.

The project is conducted in the Boletice Military Training Area (BMTA), which includes headwaters of

the Blanice River and its tributaries. Blanice River basin is crucial for freshwater pearl mussel

conservation, as it is inhabited by the largest freshwater pearl mussel population in the Czech

Republic that is one of the largest populations in Central Europe.
