Relevant Information:

Description: Anal soft rays: 25 - 30. Dorsum dull grey with pale green iridescence; maxillary band of teeth forms a continuous row with no break in midline. Snout protruding with upper jaw tooth bands partly exposed when mouth is closed; large median vomerine tooth plate. Habitat: Occurs in large rivers and enters flooded forests. Found in rapids and in deep slow reaches. Migrates into the middle Mekong along the Thai-Lao border as water levels and turbidity begin to increase. Reproduction: Reproduces early in the flood season and juveniles of 6 to 7 cm are taken by late June. Diet: Juveniles feed on prawns and insects; subadults and adults on prawns, insects and particularly mollusks which are more predominant in stomach contents than in any other Pangasius species and on plants. Etymology: The specific name conchophilus: concho, from concha (Neo-Latin), and kónche, mussel or cockle; phílos, fond of, referring to its “pronounced molluscivory”.

IUCN Red List

A common species, it is recorded from the Chao Phraya and Bangpakong rivers in Thailand, and the Mekong basin. It is highly utilised and impacted by habitat loss, but is assessed as Least Concern at present as there is no evidence at present of significant population declines across its range. Impacts from potential future mainstream dams should be monitored, but needs updating (IUCN 2012).
