Etymology: mystus: Probably from the Greek "mustes" which literally means "initiated in the mysteries" (Ref. 43912).
More on author: Linnaeus.
Taxonomic Remarks
This species was commonly known as Schilbe (Eutropius) niloticus; the morphological examination of the holotype of Silurus mystus Linnaeus, 1758 (De Vos and Skelton, 1990) has shown that this specimen and Schilbe (Eutropius) niloticus Rüppel, 1829 belong to the same species; this results in the substitution of the name S. niloticus by the oldest name available, in this case, S. mystus.

; 淡水 居于水底的; 河川洄游 (Ref. 138143); 深度上下限 4 - 69 m. 熱帶; 23°C - 27°C (Ref. 1672); 25°N - 27°S, 17°W - 45°E
Africa: Nilo-Sudanese species, known from the Nile basin and in West Africa from the Senegal River eastwards to the Cross, Wouri and Sanaga River, including the Chad basin (Ref. 43912). Various reports, including from the Ogowe and Congo River basin or Zambia and Zimbabwe, are based on misidentifications (Ref. 43912). Reports from Angola and Tanzania are questionable and need confirmation.

Anterior nostrils more closer to each other than to posterior ones; inner margin of pectoral-fin spine strongly denticulate posteriorly (Ref. 43912, 57127, 81643). Nasal barbel reaching to anterior eye margin (Ref. 57127, 81643), but never extending beyond posterior margin of eye (Ref. 43912, 57127, 81643). Mouth subterminal (Ref. 57127, 81643), snout reaching beyond lower jaw (Ref. 43912). 45-64 branched anal-fin rays and 8-15 gill rakers on lower limb of first gill arch (Ref. 43912, 57127, 81643).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Lacustrine as well as fluviatile species, confined to lakes and moderate to large rivers (Ref. 43912). Adults shoal in standing or slowly flowing open water with emergent or submerged vegetation. Generally more active at night or in subdued light. They feed from mid-water and surface waters on a wide variety of foods including fish, insects, shrimps, snails, plant seeds, and fruit. Oviparous, eggs are unguarded (Ref. 205). Often important spawning migrations occur (Ref. 43912). They breed during the rainy season and may be either a single or multiple spawner in different localities, laying eggs on vegetation. May live up to 6-7 years (Ref. 7248). Max total length 45.0mm (Ref. 43912). Also caught with drawnets. In general considered as a flavoured, first class eating fish (Ref. 43912).
也用拖网捕获。 游入不流动或慢慢流动的开放水域，水面与水下有植物生长的地方。 通常较活跃的在晚上或在减弱的光线中。 在各式各样的食物包括鱼，昆虫，虾，蜗牛，植物种子与果实上从中层水域与水表面觅食。 卵生的.(参考文献 205) 在雨季期间进行繁殖而且可能是或一或者在被在植物上产卵的不同的地点中的多只产卵鱼。 可以活超过 6-7 数年。 (参考文献 7248)
