Actinopterygii 辐鳍鱼纲 (条鳍鱼)
(Catfish) > Schilbeidae
Etymology: mystus: Named for Mr. Adanson, collector of the type material of this species (Ref. 43912). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
; 淡水 居于水底的; 河川洄游 (Ref. 51243); 深度上下限 4 - 69 m. 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.
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 13.1, range 15 - ? cm
Max length : 35.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 57127); 最大体重: 250.00 g (Ref. 3799); 最大年龄: 7 年 (Ref. 7248)
背棘 (总数): 1; 背的软条 (总数): 6. Diagnosis: adipose fin present (Ref. 43912, 57127, 81643) and fully developed (Ref. (Ref. 57127, 81643). 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).
Lacustrine as well as fluviatile species, confined to lakes and moderate to large rivers (Ref. 43912). Shoals in standing or slowly flowing open water with emergent or submerged vegetation. Generally more active at night or in subdued light. 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). 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).
