Rationale
(Changed due to Same category and criteria)
This subspecies has a wide distribution within southern Africa, with no known major widespread threats. First assessed in 2009 as Least Concern globally, regionally as Least Concern for southern Africa, but regionally vulnerable due to fishing pressure in East Africa. This species status was re-evaluated for Southern Africa during the Southern African Freshwater Fish assessment in 2016 and new information has not resulted in a change in status.The regional Southern African and Global status therefore remains Least Concern. The status of this taxon in East Africa requires reassessment.
Distribution
This subspecies is found on the coastal plain rivers of the east African coast from Mozambique to South Africa.
Eastern Africa: It occurs in the Lower Shire River, Malawi.
Southern Africa: This subspecies is known from the Mkuze River in KwaZulu-Natal to the central plains of Mozambique. In Zimbabwe it occurs in the lower Save-Runde system and lower sections of some Zambezian tributaries, such as the Mazowe (Bell-Cross and Minshull 1988).
This subspecies is widespread and abundant in areas surveyed within the Niassa Reserve.
Threats
This subspecies is fished for consumption, as well as sport. The spread of Oreochromis niloticus is a potential threat although interbreeding between the two species has not yet been reported.
Uses and trade
This subspecies is fished for consumption, as well as sport.
Conservation
Maintenance of pure stocks in refuge areas may be needed to protect this species, as well as the control of the spread of Oreochromis niloticus. Population trends should be monitored.
