Young mussel recovery Besides the improvement of the habitat, the rejuvenation of the mussels is one main goal of the project. The recovery of young mussels shows that the actions for mussel protection work. |

| Freshwater pearl mussel Before the cleaning of sediment the brook is thoroughly searched for mussels in order to place them in adjacent brook sections until after the measure. On this occasion, more than 50 young freshwater pearl mussel were collected. They are barely visible in the brook gravel and are thus difficult to detect (see circle). This rare recovery of naturally grown young mussels raises great hope that it will be possible to preserve the freshwater pearl mussel in the tri-border region on a long-term basis. |

| Common river mussel Minnows and chubs are electrically caught in the brook, infected with larvae of the common river mussel and released again. After four weeks the young mussel falls off of the fish. In this way, about 115,000 young mussels were released. In the year 2007 four year old common river mussels were found. They derive from the artificial infection of the year 2004. |
