Ocean fishing stocks are running out, and Asian fish farms are being asked to fill the gap left by trawler fleets that now travel further, longer, and deeper to find a catch. This 101 East episode follows that shift into aquaculture, visiting fish farms across Asia to see how quickly the industry has grown to meet rising global demand for seafood. Interviews with workers, industry figures, and officials lay out what fish farming actually costs: pollution running off into surrounding waters, disease spreading through crowded pens, and labor conditions on farms and processing lines that go largely unchecked. The film treats the central question directly, is fish farming a genuine replacement for an ocean that can no longer support current demand, or does it just move the damage onshore. No single farm or country is held up as a model; instead the episode moves between operations to show a pattern of the same environmental and health problems recurring wherever aquaculture expands fastest.
