Pomadasys panamensis has been assessed as Least Concern.  This species is widespread in the eastern Pacific region and is common throughout its range. There are no known major threats to this species, and no current indication of population decline from commercial fishing activities in some parts of its range.

Habitat and Ecology [top]

Habitat and Ecology:Pomadasys panamensis is a demersal species that inhabits the sandy substrata of coastal waters (McKay and Schneider 1995) to depths of around 100 m.  In a survey conducted at Gorgona Island, Colombia, this species was considered occasional in rocky substrata, and abundant in sandy substrata (Rubio 1986).   In Golfo de Nicoya, Costa Rica, this fish was considered to be a transient species in an estuary associated with mangroves (Rojas et al. 1994).  It occasionally occurs in middle estuaries and mangroves along the tropical Eastern pacific (Cooke 1992).

Use and Trade [top]

Use and Trade: Pomadasys panamensis is considered to be important for commercial fishing in Gulf of Montijo, Panama (Vega 2004), as well as in El Salvador.

Threats [top]

Major Threat(s): Although not considered a major threat to global populations at this time, Pomadasys panamensis is considered to be important for commercial fishing in Gulf of Montijo, Panama (Vega 2004), as well as in El Salvador.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Pomadasys panamensis. However, it may be present in some marine protected areas in  Peru, Ecuador, Colombia, Panama, Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala and Mexico (Roca et al. 2003).

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
