Stingrays are kept in touch pools and display tanks at aquariums and tourist attractions worldwide. Their complex sensory biology and behavioral needs raise important welfare questions for captive settings.
Touch pool stingrays face a distinctive welfare situation created by the combination of continuous handling by visitors and the removal of their barb as a safety measure for humans. Barb removal causes injury and leaves the animal without its evolved defensive structure; declinated stingrays cannot deter handling or protect themselves. Continuous handling by visitors causes physiological stress responses measurable through cortisol elevation. Electric fields from pump motors and tank equipment may cause sensory interference through electroreception systems. Well-managed observation tanks that allow natural resting and burying behaviors, avoid barb removal, and limit visitor contact represent a superior welfare approach to touch pools, and an increasing number of aquarium professionals are moving in this direction.
