* Aquariums don't require direct access to the ocean. They primarily rely on freshwater sources, which landlocked countries typically have access to through rivers, lakes, and groundwater.
* Water is transported. While a landlocked country might not have access to the ocean, they can transport saltwater in large quantities using tankers or pipelines.
* Freshwater aquariums are common. Many aquariums focus on freshwater ecosystems, showcasing the diverse range of fish, plants, and invertebrates found in rivers, lakes, and swamps.
* Artificial saltwater environments are possible. Aquariums can create artificial saltwater environments using carefully controlled systems that mimic the conditions found in the ocean.
Examples:
* The National Aquarium of Malawi (Malawi is a landlocked country in southeast Africa) showcases the unique freshwater fish found in Lake Malawi, one of the largest lakes in the world.
* The Denver Aquarium (Denver, Colorado, is landlocked) has exhibits featuring diverse marine life, including sharks, rays, and jellyfish, all maintained in carefully controlled saltwater environments.
While it might be more challenging to maintain an aquarium with extensive ocean exhibits in a landlocked country, it is certainly possible to build a successful aquarium showcasing diverse aquatic life, both freshwater and saltwater.
