Foto de stock - 28 September 2023, Saxony, Adorf: Hydrobiologists Felix Grunicke (l) and Thea Hose from Dresden University of Technology release young river pearl mussels into the water at the Triebel River in the Vogtland region. 250 mussels from a captive breeding program were released into the wild. The freshwater mussel is threatened with extinction. For several years, the animals have therefore been bred in a station in the Vogtland district. It is one of four such facilities nationwide. Without this human help, the animals would have become extinct in Saxony, according to experts. Photo: Hendrik Schmidt/dpa. - Adorf/Saxony/Germany
