Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Perciformes Nandidae

Scientific Name: Nandus oxyrhynchus Ng, Vidthayanon & Ng, 1996
Taxonomic Notes: This species was described from the Mun River drainage, a major tributary of the Mekong River in eastern Thailand (Ng et al. 1996). It was previously misidentified as N. nandus (a species known only from the Indian subcontinent) in older literature.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1

Population [top]

Population:There is no detailed information available on the population and its trends for this species, but data from field surveys indicate that it is an abundant species.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:UnknownPopulation severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits slower-flowing streams and rivers, as well as lentic habitats such as lakes, reservoirs and ponds. It is a carnivorous species that feeds primarily on small fishes and larger aquatic invertebrates.

Use and Trade: This species is used as a food fish in artisanal fisheries, and is occasionally exported as an ornamental fish.

Threats [top]

Major Threat(s): The threats to this species are unknown, since there is no information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. The current threats to aquatic biodiversity in all of its known distribution have also not been adequately identified.

Conservation Actions [top]

Conservation Actions: Despite being an abundant species, more information on on the distribution, biology and potential threats for this species is needed.
