The distribution of this species in the Eastern Pacific is uncertain. It is reported to occur from Costa Rica to Peru, but both the northern and southern extent is doubtful. This estuarine and freshwater species is under serious threat from coastal development and habitat destruction throughout its range, and from indiscriminate fishing with gill nets. However, more research is needed on this species' distribution, population, and habitat status. It is listed as Data Deficient.

Habitat and Ecology [top]

Habitat and Ecology:This demersal species is found in coastal, brackish and freshwater to depths of 20 m. It moves up into freshwater as adults (Cooke and Tapia 1994).
Systems:Freshwater; Marine

Threats [top]

Major Threat(s): This species is caught incidentally in small commercial fisheries, and is marketed fresh. This species is most common in shallow coastal and estuarine waters, and moves upstream as adults. Both of these habitats are under serious threat from coastal and riparian development and pollution. Adults are also under serious threat from illegal gill netting in rivers.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for this species. More research is needed on this species' distribution, population status, habitat requirements and status, and threats.
