Aquatic turtles including red-eared sliders are popular but frequently poorly kept pets whose welfare requirements are complex and often unmet, while the wild trade in turtles for food and traditional medicine poses significant conservation and welfare concerns.
Aquatic turtle welfare failure in captivity is widespread because the animals are frequently purchased as small, cheap juveniles without buyers understanding their adult size, lifespan (50+ years), and complex care needs. Inadequate UV lighting causes metabolic bone disease. Insufficient water quality causes bacterial infections. Small tanks cause physical restriction and psychological stress. The long lifespan means that poorly kept turtles suffer for decades. Aquatic turtle welfare in the wild is threatened by overharvesting for food and medicine markets in Asia, where turtle populations have collapsed across numerous species. The combination of captive welfare failure and wild population depletion makes turtle welfare one of the most serious reptile welfare issues globally.
