Wild dolphin welfare depends on clean seas, abundant prey, minimal boat disturbance and freedom from entanglement, pollution and noise that disrupt their complex social lives.
Wild dolphin welfare is compromised by multiple interacting anthropogenic pressures that disrupt their essential activities of feeding, reproducing and maintaining social bonds. Bycatch mortality is an acute welfare event — dolphins caught in nets experience drowning deaths that represent significant suffering. Chronic noise pollution interferes with the echolocation essential for dolphin hunting and social communication, creating ongoing sensory stress. Responsible dolphin watching tourism following established guidelines causes minimal disturbance while generating conservation funding and public engagement. The cumulative welfare impact of pollution, bycatch, noise and disturbance on wild dolphin populations requires systemic reduction through fishing practice reform and marine protection.
