Farmed shrimp are produced at very high densities in pond systems globally. Water quality management is the primary determinant of shrimp welfare in these intensively managed systems.
Shrimp welfare in pond systems is largely a function of water quality management. At the scale of billions of animals, even small improvements in dissolved oxygen management or disease prevention represent enormous aggregate welfare gains. The mass mortality events that periodically devastate shrimp farms - WSSV outbreaks killing millions of animals, EMS events wiping out entire pond cohorts - represent acute welfare disasters of enormous scale. Prevention-focused biosecurity, better stocking density management and improved water quality monitoring are both welfare and production priorities, with their alignment providing market incentive for improvement.
