Population [top]

Population:This species is common in many parts of its range.

This species was studied in different sites at Galapagos archipelago, with an overall mean abundance of 0.94 ind./500 m2 (Edgar et al. 2004). This fish was studied in Gulf of Papagayo, Costa Rica (Dominici-Arosemena et al. 2005) with a density < 0.01 ind./ m2. At Gulf Dulce, still in Costa Rica, it had a density <0.001±0.002 ind./ m2, - relative abundance of 0.023% (Figueroa, 2001). Within a five-site-study survey, at Catalinas Islands, this fish could not be observed (Espinoza and Salas, 2005). According to Aburto-Oropeza and Balart (2001), M. bairdii is a rare species at Los Islotes, Gulf of California (accounted less than 0.01% of total abundance) with an occurrence frequency below 10%. In Cabo Pulmo, Mexico, this fish was not found, although it has already been recorded there (Villarreal-Cavazos et al. 2000). A survey at Gorgona Island coral reefs, Colombia (Rubio, 1986), showed that this fish seems to be occasional in coralline, rocky and sandy bottoms.
Current Population Trend:Unknown

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits rocky inshore reefs exposed to wave action and currents to depths of 15m, and is most frequently observed near large boulders in the shallow subtidal zone. At Gulf of Chiriqui, Panamá, this fish can be found in massive corals and exposed shallow rocky reefs (Dominici-Arosemena and Wolff, 2006).

Threats [top]

Major Threat(s): There are no major threats known for this species. According to Dominici-Arosemena et al. (2005), this is a important aquarium fish in Gulf of Papagayo, Costa Rica, however this is unlikely to significantly affect the population.

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).
