Scientific Name: Chetia brevis
Species Authority: Jubb, 1968
Common Name/s:
English Orange-fringed River Bream

Assessment Information [top]

Red List Category & Criteria: Endangered   B1ab(iii,v)+2ab(iii,v)   ver 3.1
Year Published: 2007
Assessor/s: Engelbrecht, J. & Bills, R.
Reviewer/s: Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Unit)
Justification:
This rare species has an estimated extent of occurrence (EOO) less than 5,000 km². Its area of occupancy (AOO) is less than 500 km². Given the main threats of alien fish predators, subsistence fishing, and impacts from agricultural activities, fewer than five locations are estimated for the species. The alien fish species Serranochromis robustus continues to spread throughout the lower Lomati and Komati River systems; continuing population declines are anticipated.
History:
1996 Vulnerable
1994 Rare (Groombridge 1994)
1990 Rare (IUCN 1990)
1988 Rare (IUCN Conservation Monitoring Centre 1988)

Population [top]

Population: A rare species - typically encountered in ones and twos in riverine habitats. Does very well in Dams (e.g., Driekoppies and Lomati Draai Dam).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Slow flowing vegetated sections of rivers and backwaters. Artificial dams.
Systems: Freshwater

Threats [top]

Major Threat(s): River regulation (continuous high flows) of the Lomati River. Serranochromis robustus is spreading through the lower Lomati and Komati River systems. Subsistence fishermen do target this species as they are easily caught on baited hooks.

Conservation Actions [top]

Conservation Actions: Benign introductions made into one dam in Kruger National Park already successfully made. Introductions into irrigation dams in the Lomati catchment are suggested.
