Legislative Action and Key Details

The Mexican Chamber of Deputies has approved a reform to the Wildlife General Law that prohibits the use of marine mammals, including dolphins and whales, in any type of show. The unanimous vote took place during an extraordinary session on Thursday morning.

The reform adds and amends articles 47 Bis 4, 60 Bis, 122, and 127 of the Wildlife General Law. These changes focus on prohibiting the exploitation of marine mammals for any purpose, whether subsistence or commercial. The project of decree now moves to the Executive branch for publication.

Key Provisions of the Reform

  • No exploitation for profit: Marine mammals cannot be subject to exploitation with the purpose of generating profit.
  • Scientific research exception: Exploitation for scientific research aimed at protecting and conserving the species is permitted.
  • Reproduction for conservation: Marine mammals can be used for breeding to conserve, recover, reintroduce, or replenish endangered species or populations.
  • Rescue and rehabilitation: Marine mammals rescued and handed over to competent authorities without profit-making intentions are covered by this reform.

All scientific research must be conducted or endorsed by a registered academic or research institution with an authorized protocol from the Secretariat of Environment and Natural Resources.

Specific Regulations for Cetaceans

  • Marine enclosures: Cetaceans must be kept in marine enclosures rather than concrete structures like pools or tanks.
  • Open installations: If marine enclosures are not feasible, cetaceans must be housed in open facilities with continuous water exchange from external sources such as tides or pumping systems.
