Sweetfish Only Grow In Japan

Ogata’s Fish Farm – A commercial Ayu fish farming business in Tonda, a couple hours outside of Osaka, Japan. Ogata’s fish farm is a sustainable business for profit, but how does it affect the health, or contribute to polluting the ocean? I spent time with Ogata, filming and documenting what is required to operate an sustainable fish farm, and how does it affect the nearby coastal waters.
