Dorosomatidae (Gizzard shads and sardinellas)
Etymology: Sierrathrissa: Latin, serra = saw + Greek, thrissa, -es = shad (Ref. 45335); leonensis: The generic and specific names make allusion to the known geographic range of this genus and species (Ref. 121309).
Environment: milieu / climate zone / depth range / distribution range
生态学
; 淡水 大洋性; 深度上下限 0 - 8 m (Ref. 188). 熱帶; 18°N - 0°N
Africa: rivers of West Africa (Ref. 188), from Senegal to Cameroon (Ref. 3509), including Senegal, Gambia, Bia and Niger rivers (Ref. 81269), and Wouri and Sanaga rivers in Cameroon (Ref. 51193, 81631); also in the man-made lakes Kainji in Nigeria and Volta in Ghana (Ref. 188, 81269).
非洲: 塞內加爾到喀麥隆, 顯然地在河的下游與上游中, 但是後者只在尼日的案例下被確認; 也人造的卡因基湖 (奈及利亞) 與佛塔河 (迦納).
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 2 - ? cm
Max length : 3.5 cm SL 雄鱼/尚未辨别雌雄; (Ref. 130826); common length : 2.3 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数) : 0; 背的软条 (总数) : 12 - 15; 臀棘: 0; 臀鳍软条: 16 - 20; 脊椎骨: 36 - 41. Diagnosis: Small, slender fishes, easily mistaken for the juveniles of Pellonula (Ref. 188). Belly rounded, with 0-10 minute pre-pelvic scutes, without arms, supporting a low membranous keel, post-pelvic scutes similar, the keel more apparent, and a W-shaped scute located at the pelvic fin bases; lower gillrakers 13-16; pelvic insertion well before dorsal fin, with 1 unbranched and 5-6 branched rays; anal fin beginning under dorsal fin base (Ref. 188, 2849, 81269, 81631, 120915, 121309). It commmonly occurs with Pellonula, which has pelvic fins with 1 unbranched and 7 branched rays, normal scutes and the pelvic fin insertion more or less below the dorsal fin origin (Ref. 188).
小又细长的鱼, 容易地 Pellonula 被误认为稚鱼了。 前腹鳍鳞甲细小的,4 到 10, 没有被支撑一个低的膜状龙骨脊，在腹鳍之后的鳞甲的手臂相似的, 龙骨脊更明显的。 腹鳍嵌入在背鳍正前方; 在背鳍基底下面的臀鳍开始。 鳞片显然地除了近的尾部以外不存在。 颚大约相等, 有小的齿。
A riverine species, but also in man-made lakes (Ref. 188). Schooling in open waters and at about 2 to 8 m in Lake Kainji, rising to about 30 cm from the surface at night in Lake Volta (Ref. 188, 3034). It feeds on plankton, especially cladocerans and rotifers (Ref. 188, 120915). It breeds at about 1.8-2.0 cm standard length (Ref. 188).
出现于河也在人造的湖中。 在开放的浅水域内形成鱼群,上升在湖佛塔河中在晚上到大约 30 公分。 吃浮游生物, 尤其水蚤。
