Sterlet, a breed of sturgeon, swim in a tank at the Beloyarsky state fish hatchery in the village of Izykhskiye Kopi in Khakassia region, August 18, 2014. The hatchery was built to replace fish stocks in the Yenisei River depleted after construction of a hydro-electric dam, which blocked their migration route. The hatchlings are loaded into container trucks, and then released back into the Yenisei river about 800 km downstream from the hatchery. The hatchery will this year release 800,000 sturgeon fry back into the river, employees said. Picture taken August 18, 2014.
