Salmon fry are seen in an oxygen bag in a hatchery near the German town of Nuestadt October 22, 2013. Members of Czech Fishing Union and Bohemian Switzerland National Park release salmon every year to Kamenice river as part of the reintroduction programme kicked-off in 1998. The programme is aimed at stabilising the salmon population in the Czech Republic and at reintroducing the fish to rivers after almost 50 years of absence caused by massive industrial pollution during the communist era.
