Stock Photo - 04 November 2020, Brandenburg, Uckerland/Ot Wolfshagen: Jannis Renke, who works at the Institute for Inland Fisheries in Potsdam-Sacrow (IFB), who is completing a voluntary ecological year, brings two plastic buckets with young salmon about six to ten centimetres long to a barge. The boat then headed towards Klein Linde a few kilometres away, where the fish were released in the Stepenitz. In total, around 50,000 six-month-old salmon bred in Denmark for Brandenburg were released in the river's catchment area. The fish are released in autumn to get used to the water, feed on small crabs and insect larvae, migrate towards the open sea in spring and return to their Brandenburg home after two to three years. The reintroduction project for salmon and sea trout, initiated together with the Brandenburg State Angling Association, has been in existence for more than 20 years. Since the first stocking in 1999, about 1.19 million salmon and 1.56 million trout have been released. Photo: Soeren Stache/dpa-Zentralbild/ZB. - Uckerland/Ot Wolfshagen/Brandenburg/Germany
