The welfare of dolphins in captivity remains one of the most scientifically and ethically contested areas in animal welfare, with evidence of significant challenges in meeting the species' complex needs.
Dolphin welfare in captivity presents challenges that are difficult to fully resolve. The species' cognitive sophistication, complex social structures, and acoustic environment needs are poorly replicated in even the best-designed modern facilities. Evidence of chronic stress in captive dolphins includes suppressed immune function, stereotypic swimming patterns, and the well-documented phenomenon of animals that persist in social groups but show signs of relationship disruption. The welfare assessment debate centers on whether the cognitive complexity that makes dolphins so fascinating also makes captivity inherently problematic, regardless of facility quality - a question with significant policy implications for both existing facilities and future bans.
