Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2016-06-29
Assessor(s): Sparks, J.S.
Reviewer(s): Raminosoa, N., Randrianizahaisa, H., Rasoloariniaina, R, Ravelomanana, T. & Velosoa, J.

Facilitator/Compiler(s): Darwall, W.R.T.
Justification:
The reported range of this species extends from the Ifasy River southwards to the Anjingo River. Prior to the mid 1990s this species had not been recorded from collections in decades. It is very patchily distributed over this region with an extent of occurrence (EOO) of 4,600 km2. While the Anjingo subpopulations have to deal with both habitat degradation, as well as exotic competitors and predators, the more northerly subpopulations currently do not. Despite the apparent lack of immediate threats to the subpopulations from basins to the north of the Anjingo River, the restricted EOO and number of known locations (four) for this species, combined with the high degree of habitat degradation in the region, justifies its classification as Endangered.

Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Teramulus waterloti was recorded in the middle reaches of the Anjingo river. The flowing water was clear, the river bottom was dominated by sand. Teramulus waterloti was also sampled from a small lake and marsh. The water was turbid and the bottom was muddy.
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Unknown

Use and Trade [top]

Use and Trade: Local fishers used mosquito nets to fish in shallow lakes or marshes and took every fish for local consumption.

Threats [top]

Major Threat(s): This species is primarily threatened by habitat loss (e.g. sedimentation following deforestation), introduction of exotic fishes, including Channa maculata, and overfishing.

Conservation Actions [top]

Conservation Actions: No active conservation in place. As there are two geographically separated sub-populations taxonomic study is recommended.
