World Animal Protection (WAP) raised concerns after it discovered Morgan, Loro Parque’s only female orca, was still participating in shows as recently as the past fortnight.
Tui Group’s animal welfare policy prevents the business from promoting or selling attractions where animals are bred for commercial purposes.
"Our audits are designed to set a new benchmark for cetacean welfare in the tourism industry," it says. "They prohibit, among other things, breeding for commercial purposes, the use of drugs for behavioural modifications, the capture of cetaceans in the wild, and the use of food deprivation techniques."
