Scientific Name: Paretroplus maromandia Sparks & Reinthal, 1999
Taxonomic Notes: Note the species name is maromandia not maromamdia (see FishBase).

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iii,iv) ver 3.1
Year Published: 2016
Date Assessed: 2016-07-02
Assessor(s): Sparks, J.S.
Reviewer(s): Randrianizahaisa, H., Rasoloariniaina, R, Ravelomanana, T. & Velosoa, J.
Contributor(s): Loiselle, P.V.
Facilitator/Compiler(s): Darwall, W.R.T.
Justification:
This species is known only from the Andanomalaza and Maevarano river basins in northwestern Madagascar (and was present in Lac Andrapongy until the mid-1990s; that population is now considered extinct) (Sparks, 2008). It has an estimated extent of occurrence of less than 5,000 km² and is limited to two, possibly three, locations in a highly fragmented habitat. Habitat loss/decline due to deforestation continues and the species is also impacted by competition and predation from introduced exotic fish species. This species is uncommon throughout its restricted range (J. Sparks, pers. obs.). The species is therefore assessed as Endangered. The status of the Maevarano River population is unknown (the species was not found there on most recent survey in 2011) which, if confirmed extinct at that locality, would change the status to Critically Endangered.

Population [top]

Population:The type series of P. maromandia was collected from the Maintsomalaza River, which is the local Malagasy name for the river just downstream from the confluence of the Manongarivo and Andranomalaza rivers, in the immediate vicinity of the town of Maromandia along the northwest coast of Madagascar (Sparks and Reinthal, 1999; Sparks, 2008). Local fishermen report catches of the new species from estuaries in the area and from the Andranomalaza River (Nourissat, 1998). Additional specimens were collected from the Andranomalaza River in 2011 (J. Sparks, pers. obs.).
Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Occurs in these large, tidally influenced rivers that are generally shallow, the water relatively clear, and with a slow to moderate current. The substrate comprised mostly sand and silt, although in places was extremely muddy (Sparks, 2008).
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: A highly sought after food fish that is consumed locally.

Threats [top]

Major Threat(s): Deforestation and resulting habitat degradation, as well as overfishing and exotic species, are threats to this species.
