IUCN Red List

Hemibagrus maydelli is assessed as Least Concern because of its wide distribution which exceeds the threshold for any threatened category. However, it is essential to note that the species has not been recorded from upper reaches of Krishna river in Maharashtra and from its type locality after its first report. Furthermore, the areas from where Hemibagrus maydelli is recorded is threatened by urbanisation, industrialisation and mining activities and the species is also subject to overfishing and trade at national level, and needs updating (IUCN 2011).
