Hyalella azteca is found across Central America, the Caribbean and North America, [2] as far north as the Arctic tree line. [1] It lives among vegetation and sediments in permanent bodies of freshwater, including lakes and rivers, [1] extending into tidal fresh water, and freshwater barrier lagoons. [2]
The surface and cave forms of the Mexican tetra have proven powerful subjects for scientists studying evolution. [28] When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and ...
The Aztec chub or Aztec shiner, [1] (Aztecula sallaei) is a cyprinid fish endemic to Mexico. It is the only species in its genus. References Froese, Rainer ...
Chalchiuhtlicue was highly revered in Aztec culture at the time of the Spanish conquest, and she was an important deity figure in the Postclassic Aztec realm of central Mexico.

These lakes were drained by Spanish settlers after the conquest of the Aztec Empire, leading to the destruction of much of the axolotl's natural habitat. As of 2020, the axolotl was near extinction [6] [7] due to urbanization in Mexico City and consequent water pollution, as well as the introduction of invasive species such as tilapia and perch
Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [2] ocean acidification [3] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in water temperature, water flow, and fish habitat loss. [4] These effects vary in the context of each ...

Fish from each spawn will be taken and held at the station for future broodstock, ensuring genetic diversity. Different pairs of each species are spawned each year, discouraging spawning of the same fish year after year. The success the center has experienced in spawning is evident in its distribution of the species into their natural habitat.
