According to a Japanese specialist, both Japanese Koi fish and Vietnamese Tam Duong carp fish must be in clean water in order to survive. If their habitat is polluted, then they will die.
Nguyen Tuan Anh, Chairman of the Board of Directors of the Japan-Vietnam Environment Investment JSC, says the release of the fish proves that the treated water in To Lich river is of a good quality and can ensure the development of creatures such as fish.
