A baby dolphin was recently born inside the Dolphin Discovery facility in Puerto Aventuras, a development that has sparked confusion among locals and visitors who believed captive breeding was no longer allowed in Mexico. The reaction is understandable. In June 2025, Mexico approved sweeping reforms to the General Wildlife Law that explicitly prohibit the breeding, capture, and commercial use of marine mammals for entertainment. So how did a calf arrive in the middle of a nationwide phase-out?
The Law Exists but Enforcement Rules Do Not … Yet

The reforms passed last year make it illegal for any facility to intentionally breed dolphins or introduce new animals into captivity. However, the law gave federal agencies 365 days to write and publish the detailed regulations that determine exactly how facilities must comply and how enforcement will work. Mexico is still in that transition period.
Because of this gap, dolphinariums across Quintana Roo, including the one in Puerto Aventuras, continue operating under their existing permits. Pregnancies that occurred before (or during) this period are not currently penalized, and in many cases, the births were already in progress before the law took effect.
What the Future Holds for Dolphins in Puerto Aventuras
Once the enforcement guidelines are finalized (expected mid-2026), the landscape will change permanently:
• No new dolphins may be bred, purchased, traded, or captured.
This means the newborn calf will be part of the last generation of dolphins legally held in Mexico.
• Facilities will have to transition away from entertainment-based programs.
Foot pushes, rides, kisses, and tricks are expected to be phased out.
• Remaining dolphins will stay in human care for life.
Releasing captive-born dolphins into the wild is not considered safe or ethical by marine scientists.
• Sea pens, not concrete pools, will be the required environment.
Puerto Aventuras already uses ocean pens, which aligns with the direction of the new law.
What This Means for the Community
For Puerto Aventuras, the recent birth underscores an uncomfortable truth: the dolphin-swim industry is still operating, but its days are numbered. The calf will likely live its entire life inside Dolphin Discovery, but it will also represent the end of an era. As Mexico moves toward a conservation-based model, no more calves should be born once the enforcement rules take effect.
No, the Dolphins in Mexico Will Not Be Returned to the Wild
One of the biggest misunderstandings circulating right now is the idea that Mexico’s new marine-mammal law means dolphins will soon be “set free.” That isn’t happening. Marine biologists, rescue organizations, and federal wildlife authorities have been very direct about this: releasing captive dolphins would be fatal.
Most of the dolphins living in Quintana Roo’s facilities were either born in human care or have spent most of their lives in it. They’ve never hunted for live fish, learned how to avoid predators, or developed the navigation skills wild dolphins rely on to survive. Returning them to open ocean would be putting defenseless animals into an environment they are no longer equipped to handle.
For that reason, the law requires that all existing dolphins remain under professional care for the rest of their natural lives which, for some animals, could mean decades.
A Tourism Model Nearing Its End
For now, dolphin swims remain legal, and operators continue to run tours under the permits they already hold. But inside the industry, everyone knows things are shifting. Dolphin parks represent significant revenue and employment in Quintana Roo, yet conservation groups have pushed for years for Mexico to join the many countries moving away from captive cetacean attractions.
When the enforcement rules for the new law are published (likely in mid-2026) Mexico will begin a step-by-step phaseout. Interaction programs will disappear, shows will end, and facilities will transition toward observation-based, educational experiences only. No new dolphins will ever enter the system, and breeding will be permanently prohibited.
In short, travelers who book a dolphin swim today are taking part in a tourism activity that’s clearly winding down. Whether someone decides to participate or skip it, the reality is the same: this era is closing, and the experience will look very different within a couple of years, if it survives at all.
