Rationale
(Changed due to Same category and criteria)
Schilbe intermedius has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. Although it faces some local threats, particularly in eastern Africa, it has also been assessed regionally as Least Concern for Central, Eastern, Southern and Western Africa.
Distribution
Schilbe intermedius is widespread in sub-Saharan Africa.
Central Africa: It is found throughout the Congo basin (De Vos 1995).
Eastern Africa: It is present in Lakes Victoria, Kyoga, and associated smaller lakes and rivers including the Upper and Middle Akagera. It is also known from Nile River (Aswa River, Victoria Nile), Lake Albert and Semliki River. Furthermore, it has been collected in Lake Rukwa and Lake Malawi drainages and in the Malagarazi, Luiche, Wami, Ruaha, Rufiji Rivers, Galana-Sabaki and Lower Tana River systems (De Vos 1995, Seegers 1996, Seegers et al. 2003).
Northeast Africa: It occurs in the Nile system (Sudan), the Rift lakes and Shebeli system (Ethiopia), and Juba and Uebi Shebeli systems (Somalia) (Bailey 1994, De Vos 1995, Getahun 2007).
Southern Africa: It is widely distributed, only absent south of the Pongolo River (De Vos 1995).
Western Africa:Schilbe intermedius is very widespread in western Africa. This species is known from the basins of Senegal, Gambia, Casamance, Corubal and Geba. Within the coastal region between the Geba and the Sassandra, S. intermedius has been collected only in Little Scarcies. Further eastwards, S. intermedius is known from the basins of Sassandra, Boubo, Bandama, Agnébi, Comoé, Tano, Pra, Volta, Mono, Ouémé, Ogun, Niger, Chad and Cross (De Vos 1995, 2003).
It is common in suitable habitats and widespread. The population size and trend are not known, but fisheries catches are reported to have locally declined in many lakes.
Threats
Schilbe intermedius is commercially used in aquaculture. There is heavy fishing pressure but the species is highly abundant and fecund. In eastern Africa the species is also threatened by biotope changes. No serious threats have been identified outside Lakes Victoria, Kyoga and Nabugabo.
Uses and trade
This species is harvested for human consumption.
Conservation
No conservation actions are known. The population trend should be monitored.
