Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Siluriformes Sisoridae

Scientific Name: Glyptothorax davissinghi Manimekalan & Das, 1998
Taxonomic Notes: Glyptothorax davissinghi was described by Manimekalan and Das (1998) from the Karimpuzha and Paanapuzha tributaries of River Chaliyar, Kerala, India. This species is known to have taxonomic ambiguities. Shaji and Easa (2003) opined that G. davissinghi could not be separated from its closest relative, G. madraspatanum, and therefore can be considered only as a junior synonym. Similarly, K.V. Radhakrishnan (pers. comm.) mentions that G. annandalei collected from Karimpuzha had highly overlapping morpho-meristic characters with G. davissinghi and therefore the taxonomic validity of the latter is questionable.

Use and Trade [top]

Use and Trade: There is no information on the use and trade of this species. However, it is reasonable to suspect that the fish maybe used as food by the tribal communities residing along the banks of Karimpuzha and Paanapuzha (R. Raghavan and A. Ali pers.obs.).

Threats [top]

Major Threat(s): Destructive fishing practices including the frequent use of plant poisons and dynamites is one of the major threats to the fish fauna of the Karimpuzha and Paanapuzha tributaries (Baby et al. 2010).

Conservation Actions [top]

Conservation Actions: No conservation actions are in place for this species. There are plans by the local government to declare the New Amarambalam Reserve Forests to which G. davissinghi is endemic to, as a protected area.
