Chirostoma riojai
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Chirostoma riojai faces severe threats from water extraction and diversion that has dramatically reduced water levels in its native lake system. Agricultural runoff and urban pollution have degraded water quality, while introduced species compete for resources and alter the ecosystem dynamics. The species' extremely restricted range makes it particularly vulnerable to any environmental changes in its single lake habitat.
Habitat
This endemic silverside fish inhabits the shallow, alkaline waters of Lake Pátzcuaro in Michoacán, Mexico. It typically occurs in nearshore areas with aquatic vegetation where it feeds on small invertebrates and algae.
