Overview
Poblana ferdebueni, the Chignahuapan silverside is a species of neotropical silverside endemic to Mexico. This species was described by Aurelio Solórzano Preciado and Irma López-Guerrero in 1965 from a type locality of Laguna de Almoloya, Chignahuapan Lake, Puebla State, Mexico and was given the specific name ferdebueni to honour the Spanish ichthyologist Fernando de Buen y Lozano (1895-1962) who had originally proposed the genus Poblana.
Poblana ferdebueni faces severe threats from water extraction and pollution in its extremely limited range within the Lerma River system of central Mexico. Agricultural runoff and urban development have degraded water quality, while dam construction and water diversions have altered natural flow patterns. The species' restriction to a single watershed makes it exceptionally vulnerable to any environmental changes or catastrophic events.
Habitat
This endemic fish inhabits freshwater streams and rivers within the Lerma River basin in central Mexico. It requires clean, well-oxygenated waters with specific flow characteristics typical of highland Mexican river systems.
