Scientific Name: Ptychochromis grandidieri
Species Authority: Sauvage, 1882

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-06-27
Assessor(s): Sparks, J.S.
Reviewer(s): Raminosoa, N., Rasoloariniaina, R, Ravelomanana, T. & Velosoa, J.
Contributor(s): Loiselle, P.V. & Participants of the CBSG/ANGAP CAMP "Faune de Madagascar" workshop, Mantasoa, Madagascar 2001
Facilitator/Compiler(s): Darwall, W.R.T.
Justification:
This species is widespread and common throughout its current range, which extends along much of eastern coastal Madagascar. Although there are many threats effecting this species throughout its full range it appears to be quite robust. The classification could change with continued habitat degradation, so its status needs monitoring but currently it is assessed as Least Concern.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Endemic to eastern Madagascar. Widespread in both fresh and brackish water along eastern coast of Madagascar. Ptychochromis grandidieri is restricted to eastern drainages and is most commonly found at low elevations in coastal regions, although it is frequently also collected in the submontane forest zone where the species may be encountered up to 100 km upstream from the sea (de Rham and Nourissat, 2002).

Population [top]

Population:Ptychochromis grandidieri is restricted to eastern drainages and is most commonly found at low elevations in coastal regions, although it is frequently also collected in the submontane forestzone where the species may be encountered up to 100 km upstream from the sea (de Rham and Nourissat, 2002). Uniquely among Ptychochromis this species is apparently salt tolerant and occurs in brackish, as well as fresh, waters along much of the east and southeastern coastal regions (Stiassny and Sparks, 2006).
Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Ptychochromis grandidieri has a widespread distribution throughout eastern lowland coastal regions of Madagascar. Uniquely among Ptychochromis, this species is salt tolerant and it occurs in brackish, as well as fresh, waters along much of the east and southeastern coastal regions (Stiassny and Sparks, 2006).
Systems:Freshwater
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: It is a prized food fish in Madagascar.

Threats [top]

Major Threat(s): Widespread habitat loss and degradation due to deforestation and resulting sedimentation, overfishing, and the introduction of exotic species pose threats to this species.

Conservation Actions [top]

Conservation Actions: Ptychochromis grandidieri has a widespread distribution throughout eastern lowland coastal regions. Environmental degradation is pervasive throughout much of its range, yet the species remains abundant in many areas. The salt tolerance of many populations suggests that its persistence throughout the Pangalanes canal system is likely; however, highland populations appear to have undergone severe attrition.
