ISTANBUL, March 12, 2021 A fishing boat is seen on the Black Sea in Istanbul, Turkey, on March 5, 2021. The Black Sea is packed with local bottom fishes, including haddock, mullet, and turbot. There are also migrating fishes from the Atlantic Sea, such as bonito, bluefish, anchovy, and horse-mackerel. However, climate change, overfishing, and other natural causes have had tremendous adverse impacts on the stocks of fisheries and aquaculture. Restrictions related to the COVID-19 pandemic, as well as the rising costs of labor, fuel, and equipment also preoccupy the fishermen.
