Population [top]

Population: It is a common species in the shallow waters of its range (Allen 1980). It is common in rocky tide pools and on the shores of small islands nearer Panama City; it is rare in the mid-Peruvian coast (Burgess 1978). It is rare north of San Benitos Islands, Baja California, MX.

In the Galapagos Archipelago, this species had an overall mean density of 0.83 ind./500 m2 (Edgar et al. 2004). In a survey conducted at Gulf of Papagayo, Costa Rica, it had a mean density of 0.01+/-0.01 ind/m2 (Dominici-Arosemena et al. 2005). In Golfo Dulce, Costa Rica, this species had a density of 0.007+/-0.010 ind./m2, with a relative abundance of 0.118% (Figueroa 2001). Chaetodon humeralis is a common species at Los Islotes, Gulf of California, having an occurrence frequency between 10-30% (Aburto-Oropeza and Balart 2001).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This rocky reef-associated species is usually observed in pairs or small groups in rocky areas near the shore (Allen 1985). In the Gulf of Chiriqui, Panamá this species can be found over all kinds of substrata (Dominici-Arosemena and Wolff 2006). According to Rubio (1986), at Gorgona Island, Colombia, this fish is occasional in intertidal pools, frequent over rocky and sandy substrate and abundant in coralline substrata. According to Cooke (1992), C. humeralis may be occasional in middle estuaries, mangroves and bar-formed lagoons along the Eastern Pacfic coast.
Systems: Marine

Use and Trade [top]

Use and Trade: This species is rarely collected for the pet trade.

Threats [top]

Major Threat(s):

There appear to be no major threats to this species. Collection is limited and is not considered to be impacting the global population.

The population in the Galapagos Islands was apparently unaffected by the 1997/98 El Niño event.

Conservation Actions [top]

Conservation Actions: There are no species specific conservation measures in place, however its range includes marine protected areas.
