The State Fisheries Agency of Ukraine has launched a fish stocking initiative in the Zakarpattia region, successfully releasing over 40,000 brook trout and European grayling fry into various reservoirs. This significant effort aims to bolster the biodiversity of the region's aquatic life, with a focus on the endangered European grayling. The fish fry were reared at the 'Lopushno' Trout Breeding Plant and were introduced into rivers and streams within the Uzhanskyi National Nature Park, alongside the Zhdeniivka River. This initiative is part of a larger conservation strategy to protect the Red Book-listed species, which includes a fishing ban and international cooperation to ensure the grayling's survival.
