Population:	There is no known population information for Astronesthes richardsoni.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Astronesthes richardsoni is a mesopelagic species that is thought to occur at depths of up to 1,000m. It is thought that, like most species of this genus, it tends to live deeper than 500m during the day. Some, particularly smaller individuals, migrate up the water column to feed at night (Gibbs 1984). Its diet may consist of smaller fishes and crustaceans.
Systems:	Marine

Threats [top]

Major Threat(s):	There is no directed fishery for this species. Due to the deepwater and oceanic nature of this species it is unlikely to be impacted by coastal development and pollution from urban centres.
