Results focused on the crayfish protection

Great deal of the project activities is focused on raising of public awareness in the crayfish protection. Within this activity a thematic calendar and a leaflet were produced and information boards were placed.

Information boards

In the spring of 2024, a total of four permanent information boards were created and placed in the field.

At the Cetvina border crossing on the SAC Horní Malše, a permanent information board was installed warning of the occurrence and risks caused by the spread of non-native signal crayfish.

Permanent information panels with text about barriers and the risk of the spread of non-native crayfish species were placed at both modified levels on the Zákolanský stream.

The fourth permanent information board was installed in Prague's Stromovka. The board's message, titled "There is no crayfish like crayfish" is to highlight the difference between native and non-native crayfish in our waters. The City Hall city of Prague participated in the installation of the board.
