|Scientific Name:||Betta splendens|
|Species Authority:||Regan, 1910|
Betta splendens subspecies abbreviata Blanc 1963
Micracanthus marchei Sauvage 1879
|Red List Category & Criteria:||Vulnerable A2ace ver 3.1|
|Reviewer(s):||Rainboth, W., Ng, H.H. & Allen, D.|
This species is threatened by habitat degradation. Habitats across most of its range have been converted into intensive farmland, developed, or polluted, especially in central Thailand which is its centre of population. Genetic erosion from escaped farmed stock into wild habitats is a secondary threat.
Currently its exact extent of occurrence and area of occupancy are poorly known, but is locally uncommon in its suitable habitats. The species is assessed as Vulnerable due to a suspected population decline of at least 30% across its range, and a declining area and extent of occurrence.
|Range Description:||Endemic to Thailand, from the Mae Khlong to Chao Phraya basins, the eastern slope of the Cardamom mountains, and from the Isthmus of Kra.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||Locally uncommon throughout its range, suffered much decline due to habitat degradation and pollution.|
|Habitat and Ecology:||Inhabits intact marshlands in shallow zones, adaptive to paddyfields.|
|Use and Trade:||Popular in the aquarium trade and bred in many domestic variations for national and international markets, and game fighting.|
|Major Threat(s):||Habitat degradation is the main threat to the species, and most of its suitable lowland habitat has been converted into intensive farmland and urban areas, or polluted, especially in central Thailand. Genetic erosion is a secondary threat from escaped farmed stock into wild habitats.|
|Conservation Actions:||Captive breeding from wild populations is strongly recommended. Management of known habitats is also needed.|
