Darkedged Splitfin

Splitfins are among the most threatened groups: of some 15,000 freshwater fish species, around one in three are threatened with extinction.
Shoal conservation exists to address that challenge. They give critical attention, escalate support, and accelerate and intensify the action that is urgently required to stem the tide of extinction and recover endangered species populations throughout the Earth’s freshwaters.

Lagunas de Zempoala National Park

Lagunas de Zempoala National Park is a natural protected area which consists of a group of seven lagoons. In the Nahuatl language, “Zempoala” means “place of many waters.”
The lagoons of Zempoala are located in a biological corridor named Chichinautzin, between the municipalities of Ocuilan de Arteaga, at the southwestern section of State of Mexico and Huitzilac, northwestern section of the state of Morelos, 50 km away from Mexico City.
The National Park covers about 4,700 hectares (12,000 acres) and lies at an elevation of about 2,900 meters (9,500 feet) above sea level.
The Zempoala lagoons were granted the title of national park on November 27, 1936 by the president of Mexico, and the decree was modified in May 1947 to reduce the park’s territory to its current 4,700 hectares.


Darkedged Splitfin

The most endangered group of fish in the world. The darkedged splitfin Girardinichthys multiradiatus, is an endemic and Endangered fish found in Mexico. Goodeids, generally referred to as splitfins, are some of the rarest fish in the world. These tiny jewels are often confined to the smallest pools of water in the Mexican and American deserts. Because of their beauty they are frequently kept in aquaria, including many public zoos and aquaria. They have a strong following of passionate supporters but until now there has been limited action for these highly threatened species. There are approximately 50 species of goodeid. Three are found in Nevada in the US (there were four but one is extinct) and the rest are found in the Mexican Plateau. Many of the species are only found at a single location and confined to a single body of water. Two species are already extinct and three are extinct in the wild. More than 90% of the fishes are threatened with extinction, making it the most endangered group of fish in the world.
Compounding threats such as pollution, overexploitation, habitat loss and invasive species introductions are rapidly altering the conditions to which freshwater species have adapted over many millennia.
