Occurrence of the fish Girardinichthys viviparus (Cyprinodontiformes: Goodeidae) in an urban lake at Mexico City

Abstract

A population of the Chapultepec splitfin Girardinichthys viviparus was found in the urban Lake Alameda Oriente. Biometry data for females and males are presented for first time for this population. The main causes of risk reported for this species in the aquatic system are water depletion and habitat alteration by treated wastewater used to keep the water level in the lake.
