Nemateleotris magnifica has been assessed as Least Concern.  This species is undergoing localised declines in abundance due to harvesting for the aquarium trade and habitat degradation, however these threats are not known across its entire distribution.  This species has a broad distribution throughout the Indian and Pacific Oceans.  Monitoring of the regional threats and population trends is needed to ensure localised significant declines do not become more widespread.

Geographic Range [top]

Range Description:Nemateleotris magnifica is distributed from East Africa to the Hawaiian, Marquesan and Pitcairn Islands, north to the Ryukyu Islands and south to New South Wales (Randall 2005).  Fishbase (2007) states that the southern limit of this species' range extends to New Caledonia and the Austral Islands, however there is no reference to support this.

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Nemateleotris magnifica inhabits burrows on the upper portion of outer reef slopes at a depth range of 6–61 m.  This species hovers above the bottom, facing the current to feed on zooplankton: primarily copepods and crustacean larvae. This species does not stray far from its burrow, and occurs individually or in pairs.  This species displays monogamy.

Use and Trade [top]

Use and Trade: Nemateleotris magnifica is a popular aquarium fish and is harvested from the wild for the aquarium trade.

Threats [top]

Major Threat(s): Nemateleotris magnifica is a popular aquarium fish and is harvested from the wild for the aquarium trade.

This species is associated with coral reef habitats.  The coral reefs in some areas of this species' distribution (e.g., East Africa and Indonesia) have experienced localised degradation due to bleaching, industrialisation, destructive fishing practices, Crown of Thorns starfish invasions, water pollution, and other population pressures.  In other areas of N. magnifica's distribution, the reefs are in good condition, and therefore the regional degradation of the reefs is not considered a major threat to this species at present.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Nemateleotris magnifica.  However, its distribution may coincide with a number of marine protected areas.  Monitoring of regional scale threats, and population trends is needed.

Errata [top]

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