Captive sea lions are used in performances and interactions that raise welfare concerns about training methods, social disruption, and the physical demands of performances.
Sea lion captive welfare involves both the physical welfare of animals in pools that cannot replicate ocean conditions and the training methods used for performances. Historical use of food deprivation as a training motivator imposed clear welfare costs. Modern welfare-aware training uses positive reinforcement exclusively, but performances for entertainment raise questions about educational justification required by zoo legislation.
