  • Nov 2024 update: Country-wide prohibition on dolphinaria to be implemented by 2037 at the latest, but possibly sooner (there was only one remaining: Boudewijn Seapark, Bruges).

• Mexico: The Chamber of Deputies amended the General Wildlife Law in October 2022 to prohibit the use of marine mammals in commercial shows or for subsistence. Animals currently kept in captivity could be kept for the rest of their lives, but using them in shows was no longer permitted. The Mexican Senate confirmed the ban in 2023, but as of February 2024, several theme parks and aquariums were refusing to comply, using legal means to delay the law's implementation, and seeking to overturn the ban.

• Switzerland: Dolphinariums are not technically prohibited, but there have been no dolphinariums in Switzerland since 2013, and it is practically impossible to set up and run a new one. The Animal Protection Act was amended in May 2012, stipulating: "It is forbidden to import dolphins and other cetaceans (Cetacea)." Animal Welfare Act. Fedlex. Retrieved on 3 December 2024. Therefore, the last facility that still kept cetaceans in Switzerland decided to close its dolphinarium by the end of 2013. "ab 2013 ... in der Schweiz wird es keine Delphine mehr geben!"
