The Gangwon Special Self-Governing Province's Seafood Resource Center has distributed 800,000 northern clams and 520,000 improved clams to eight fishing villages on the East Coast. The clams, which were raised for six months and fed with microalgae, are expected to grow to over 10cm long within two to three years, contributing to the creation of shellfish resources and increasing fishermen's income. The center has released over 10 million northern clams and 2.4 million improved clams since 2011.
