Mexico Frees 350 Captive Dolphins Under New Animal Welfare Law

Mexico — A recent law has prohibited shows with marine animals in the country. As a result, 350 dolphins that participated in various exhibitions at Mexican recreational parks will be released. These animals, considered among the most intelligent in marine fauna, will now transition from acrobatics and public demonstrations to complete freedom.

Dolphins are aquatic mammals recognized for their complex communication systems. They are sociable, charismatic, and playful. After years in captivity, the new Mincho Law mandates improved living conditions for dolphins inhabiting different aquariums across the country.

Forced to live in small pools with chlorinated water and perform daily shows without rest, this law, promoted by the Mexican organization Animal Heroes dedicated to animal welfare, requires that these captive dolphins cease being exploited and be released into their natural habitat.

The Mincho Law

This law is named after a dolphin that sadly became a symbol of animal abuse in Mexico after suffering a tragic accident in 2020 during its act at the Barceló Hotel dolphinarium in Riviera Maya. Mincho, a bottlenose dolphin, hit concrete while performing acrobatics. Reportedly, it had vision problems and, although it needed rest, was forced to return to its activities two days after the accident.

Although this occurred in 2020, images and news of the incident went viral in 2025, leading to the creation of the Mincho Law, promoted by Animal Heroes and approved in June 2025 by the Senate and ratified by the Chamber of Deputies for the protection of these animals. The Federal Attorney for Environmental Protection (Profepa) permanently closed the Barceló Hotel dolphinarium.

Changes Imposed by This Law Include:

• Prohibition of reproduction in captivity unless for conservation or scientific rescue purposes.
• Prohibition of possession of “new” marine mammals.
• Prohibition of dolphins performing acrobatics.
• Prohibition of dolphins being kept in concrete tanks.

Freedom for 350 Mexican Dolphins

The Mincho Law has already banned shows with aquatic animals. Recall that in 2015, a federal law also prohibited the use of wild animals in circus performances. This new law also includes shows with seals, sea lions, whales, and orcas, which have long been regularly presented in aquariums across various parts of the country.

For now, a total of 350 dolphins used in shows, for recreational swimming, or for commercial exploitation will be set free. Although the announcement has been made, their release will be gradual. The centers housing these animals have an 18-month deadline to relocate them and present periodic reports demonstrating real progress.

Most dolphins will be transferred to different marine sanctuaries or saltwater corrals, thereby regaining their freedom and well-being, reducing their stress, and improving their living conditions. Each will receive veterinary care, appropriate feeding, and lifelong care.

No More Shows with Aquatic Animals

Dolphin shows were among the main attractions of aquariums and beach destinations. The Mincho Law promotes respect for marine fauna and healthy whale and dolphin watching in their natural habitat. It also raises awareness among people about the care our environment needs.

Some may miss this type of show, but ending animal exploitation is a much more necessary measure and is already being considered in places like Canada or Chile, and it is hoped it will become a reality in other countries worldwide.
