In Gümüşhane, Turkey, a unique economic venture has emerged from the farming of rainbow trout in dam lakes used for electricity generation, such as Torul Dam Lake on the Harşit River. This fish farming operation, which produces around 2,110 tons of trout per year, has become a significant economic driver, with the majority of the fish, labeled as Black Sea salmon, being exported to countries like Russia, China, Chile, and Japan. These fish are first reared in the dam lakes until they reach 1 kilogram in weight, then transported to sea coast facilities for further growth before being exported. In 2021, the total export value reached approximately 410 million dollars, showcasing the sector's contribution to Turkey's economy. Ahmet Bingöl, a senior fisheries engineer, highlights the potential for growth and expansion to new markets, with projections of 70-80 thousand tons of production for the year, aiming to further boost the economic benefits of this innovative enterprise.
