As part of efforts to restore native fish species and preserve biodiversity, 17,412 European grayling were released into water bodies in Transcarpathia, according to the State Agency for Land Reclamation, Fisheries, and Food Programs.
The fish stock was raised using state budget funds at the “Lopushno” trout hatchery, which is under the jurisdiction of the State Agency for Fisheries. The average weight of the fry was 5.45 grams.
The stocking covered water bodies important for the conservation and natural reproduction of this species. The juveniles were released into the tributaries of the Black Tisa, the Krasnoshurka River—a tributary of the Teresva—the Rika River and its tributaries, as well as into the Terelya River within the Synevyr National Nature Park.
The European grayling (Thymallus thymallus) is listed in Ukraine’s Red Book. It inhabits clean, well-oxygenated mountain rivers and serves as an indicator of their ecological health.
In the near future, the State Fisheries Agency plans to stock Transcarpathian rivers with juvenile Danube salmon (golovatitsa).
