Habitat and Ecology [top]

Habitat and Ecology: This amphidromous fish inhabits estuaries, stagnant ditches or creeks of low current velocity. It is a benthic species and is most abundant on sandy and muddy substrate (Rojas et al. 1994). It ingests mud, detritus and small fishes. This species is found typically in freshwater, but moves freely into the sea and can be regularly found in middle estuaries, mangroves, bar-formed lagoons and upper estuaries along the tropical eastern Pacific coast (Cooke 1992).
Systems: Freshwater; Marine

Use and Trade [top]

Use and Trade: This is a commercial species that may be used for aquaculture and has now begun to be semi-cultivated in marshes. It has proven extremely tolerant of variations in salinity, and traditionally has been used for food. Its ability to withstand long periods of transportation (up to three days) without refrigeration makes it attractive for marketing in isolated communities where logistical facilities are inadequate (FAO, 1987).

Threats [top]

Major Threat(s): There are no major threats known for this species.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for this species. However, this species distribution falls partially into a number of Marine Protected Areas in the Eastern Pacific region (WDPA 2006).
