Dawkinsia exclamatio is endemic to India where it is restricted to a small range and area in the Kallada River, in southern Kerala. It is found both upstream in the tributaries of Umayar and Kulathupuzhayar as well as about 2 km downstream of the Thenmala (Kallada Irrigation Project) dam on the Kallada River. The species is impacted by the exotic species Cyprinus carpio, which are regularly introduced into the dam reservoir and the species has also lost a large section (about 70%) of suitable habitat due to the construction of the dam and illegal dynamite fishing (including within the protected area that covers an estimated 80% of the species range). Based on these potential threats the species' status can be justified as Endangered.

Geographic Range [top]

Range Description:Dawkinsia exclamatio occurs in the Kallada River, in southern Kerala, India, about 12 km upstream of the area where this river meets the coastal floodplain. The species is also found both upstream in the tributaries of Umayar and Kulathupuzhayar, and about 2 km downstream of the Thenmala (Kallada Irrigation Project) dam on the Kallada River (Pethiyagoda and Kottelat 2005).

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in clear water, rock and pebble substrate areas of the upper reaches of the Kallada River.The fish's natural habitat includes both slow-flowing pools and relatively fast-flowing runs (Pethiyagoda and Kottelat 2005, R. Abraham pers. obs. January 2010).
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The species is often caught as a result of non-targeted gill-netting and is hence consumed. They are also occasionally used to bait larger fish that have consumptive use. It is collected for the ornamental fish trade.

Threats [top]

Major Threat(s): Some of the potential threats affecting Dawkinsia exclamatio are illegal dynamite fishing in the species range, including inside protected areas and negative impact by the large invasive species Cyprinus carpio, which was introduced into the dam reservoir but has now spread into surrounding areas.

Conservation Actions [top]

Conservation Actions: A large portion of this species' range falls within the protected areas of the Shendurney Wildlife Sanctuary and the Kulathupuzha Reserve Forest. Some, but not all, areas of the protected area ensure the species' survival. Life history studies and impacts of fishing need to be studied. Before describing this species, captive breeding techniques were developed for D. filamentosus from Kallada, which is currently recognized as D. exclamatio (Mercy et al. 2007).
