成熟度: Lm 13.4, range 11 - 19.5 cm
Max length : 30.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); common length : 25.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); 最大體重: 927.00 g (Ref. 3808)
背棘 (總數) : 0; 背的軟條 (總數) : 18 - 23; 臀棘: 0; 臀鰭軟條: 17 - 23; 脊椎骨: 44 - 48. Diagnosis: Body elongate, but variable in depth, belly fairly sharply keeled; with 14-20 pre-pelvic and 12-15 post-pelvic scutes, total scutes 31-34; lower gillrakers 70-166, increasing with growth; upper pectoral finrays white on outer side, the membrane between black (Ref. 188, 3259, 81269, 81631). It resembles Sardinella aurita, but pelvic fin with 1 unbranched and 7 branched rays vs. 1 unbranched and 8 branched rays in S. aurita and no black spot on hind part of gill cover, but faint gold or black area just behind gill opening (Ref. 187, 188). It is distinguished from S. rouxi by having more lower gillrakers, which is only 30-40 in S. rouxi, and the caudal fin grey, its tips almost black vs. pale yellow with distal margin dusky in S. rouxi (Ref. 187, 188, 81269).
Body shape (shape guide): fusiform / normal; Cross section: compressed.

A coastal, pelagic species, but tolerant of low salinities (Ref. 188, 5286, 27000, 86940); sometimes in estuaries and lagoons (Ref. 188, 2683). It forms schools, preferring waters of 24°C, at surface or at bottom down to 50m, strongly migratory (Ref. 188, 5286). It feeds on a variety of small planktonic invertebrates, also fish larvae and phytoplankton (Ref. 188, 27165). It breeds only once in the year, during the warm season between July and September, in coastal waters; juveniles and adults show clear north-south migrations in the Gabon-Congo-Angola sector and the Sierra Leone-Mauritania sector of the Atlantic Ocean, each area having nurseries; these movements are correlated with the seasonal upwelling (Ref. 188). It is of considerable importance off West African coasts, but combined with Sardinella aurita in most statistics, partly because both species are often caught together (Ref. 188).
在沿岸水域中形成魚群,偏愛 24個 ° C. 的水域 吃多種小的浮游性無脊椎動物，仔魚與浮游植物。 在溫暖的季節 (七月-九月) 期間進行繁殖。 稚魚與成魚顯示在加彭清楚的南北迴游-他們的範圍的剛果-安哥拉地區以及在獅子山-茅利塔尼亞的地區中, 每個區域有育幼。 運動是與季節性的湧升流有關的。 在市場上銷售生鮮地了, 冷凍或鹽醃的。
