簡短描述 型態特徵 | 形態測量圖

背的軟條 (總數): 9-11; 臀鰭軟條: 16 - 19. Diagnosis: body strongly compressed (Ref. 34290), body height 4.25-4.75 times in body length, caudal peduncle twice as height as long (Ref. 42448). Lower jaw slightly prominent (Ref. 55057). Mouth large, terminal and rather oblique, without lips or circumoral barbels (Ref. 34290), extending to below anterior border of eye (Ref. 1872, 2988, 31439). Cheek largely covered by thin suborbital bones (Ref. 2988, 31439, 34290). Branchiospines rather short but not rudimentary; pharyngeal teeth conical (Ref. 55057). Gill rakers moderately long (Ref. 2988, 31439), 16 on (lower part of) first branchial arch (Ref. 2988, 4903, 31439). Scales moderately large, 42-56 on lateral line (Ref. 34290). Lateral line descending from about upper part of gill opening to just before ventral-fin origin (Ref. 42005, 55057), more or less following the ventral body profile from ventral fin to caudal peduncle (Ref. 34290, 55057). Dorsal fin situated almost entirely above anal fin (Ref. 34290). Anal-fin base about twice as long as dorsal-fin base (Ref. 4967). 12-17 branched anal-fin rays (Ref. 4903, 34290). Pectoral fin not reaching pelvic fin (Ref. 2988, 4967, 31439, 55057). Body silver with an overall nacreous sheen (Ref. 4903, 34290), yellowish brown above (Ref. 31439). Caudal fin yellow (Ref. 2988¸4903, 31439, 34290), other fins colourless (Ref. 4903, 34290), white or greyish (Ref. 2988, 31439). Dead specimens with a distinct mid-lateral stripe (Ref. 4903, 34290), stripe silver in life (Ref. 4967).
側線在身體上的低處而且沿著尾梗的下面部份。 頰被細的眶下骨蓋著了。 銀色的有一個整體的 nacreous 光輝。 尾鰭黃色。 死的標本具有一個明顯的側面中央的斑紋。 (參考文獻 34290)

生物學特性     字彙 (例如 epibenthic)

Highly adapted to pelagic life (Ref. 12526). Found inshore and offshore (Ref. 34290). Known from the surface of inshore and coastal waters; some records from surface waters over great depth (Ref. 4903, 34291). Adults stay near the bottom during the day and near the surface at night (Ref. 34291). Juvenile fish migrate away from the shore after spending their larval stage in shallow areas (Ref. 33811). In Lake Kyoga occurring in open water away from water-lily swamps; in Victoria Nile caught in turbulent regions (Ref. 4903). Feed on zooplankton and surface insects (Ref. 4903, 12526, 34291) and eaten by birds and various fish species, mainly siluroids including Schilbe mystus, Clarias gariepinus, Bagrus docmak (Ref. 12526, 52061) and Synodontis victoriae (Ref. 125996). Mature individuals spawn in the lake and produce floating eggs (Ref. 52061). Sensitive to low oxygen conditions (Ref. 125996).

發現於岸邊了與外海.(參考文獻 34290) 稚年的魚移動在水淺的區域中花費他們的幼魚時期之後遠離海岸.(參考文獻 33811) 成魚停留在底部的附近在白天期間與晚上接近水表面處.(參考文獻 34291) 吃浮游動物 (參考文獻 13624) 與水面的昆蟲。 (參考文獻 34291) 很少達到長度大於 8 cm SL 。 (參考文獻 34290) 也用抄網捕獲。 (參考文獻 4967)
