Geographic Range [top]
Range Description: Aioliops brachypterus has been reported from Miniloc Island and El Nido Island, the Philippines. The area in which this species is known to be distributed is approximately 1,000 km². However, it is likely that this species actually occurs in coral reef habitat in a much wider range in the region.

Habitat and Ecology [top]
Habitat and Ecology: Aioliops brachypterus is found near drop-offs on coral reefs. Many species of Ptereleotridae form schools, although others occur in pairs or smaller groups (Larson 2001). This species has been found to a depth of 25 m.
Systems: Marine
Threats [top]
Major Threat(s): Aioliops brachypterus is associated with coral reef environments. The coral reefs within this species range have been degraded by human population pressures, overfishing, tourism, Crown of Thorns starfish outbreaks and coral bleaching. Coral reef habitat is also threatened by water pollution. The South China Sea is polluted by organic and inorganic wastes from sewage, from agricultural and industrial wastes, and from run-off containing oil, hydrocarbons, and heavy metals. Oil spills have caused severe marine degradation in the South China Sea, and there have been documented spills in 1992 and 1993. A combined total of 27,000 t of crude oil was released into the South China Sea from these two spills. Over 100,000 oil tankers and container and cargo vessels travel through the Straits of Malacca and Singapore each year into the South China Sea. There is therefore the potential for more oil spills in the region in the future.
The coral reefs of the Philippines have experienced the greatest degradation of all the reefs in the South East Asia. The percentage of reefs in poor condition has increased from 33% in the 1980s to nearly 40% two decades later (Tun et al. 2004). It is predicted that coral reef condition in South East Asia will continue to decline (Tun et al. 2004).
Conservation Actions [top]
Conservation Actions: There are no species-specific conservation measures in place for Aioliops brachypterus. However, the distribution of this species may coincide with El Nido Marine Reserve. Further research should be carried out to confirm the distribution of A. brachypterus and to establish its population size. Conservation measures including the establishment and management of Marine Protected Areas to reduce the rate of coral reef degradation occurring within this species range, are needed.
