A total of 15,000 Balkan trout have been relocated to rivers in the Simitli, Kresna, Katuntsi and Strumyani forest farms as part of a conservation initiative. The stocking, which involves over 100,000 fish, is being executed across 22 farms in southwestern Bulgaria by Toshkov Chark Trout Farm. The Balkan trout, a species of particular value and risk of extinction, is being reintroduced to suitable rivers annually.
