South Korea's Muan-gun province has released 11,500 mother octopuses into Tanto Bay in a move to boost the marine life and income of local fishermen. This initiative is part of a larger ₩4 billion, five-year project aimed at creating a spawning and breeding ground for octopus and releasing mother octopuses into the bay. In 2021, the project also released 31,000 mother octopuses and 800 kg of crabs, leading to the sale of about 40% of the total octopus catch by the Mokpo Fisheries Cooperative Commission by November this year.
