Short description

पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 18-21; गुदा कांटा 0; ऐनल सौफट रेज़: 17 - 23. Diagnosis: Body elongate, but variable in depth, belly fairly sharply keeled; total scutes 31-34 (Ref. 188, 81269). Lower gillrakers 70-166 (Ref. 188, 81269). Upper pectoral fin rays white on outer side, the membrane between black (Ref. 188). Sardinella maderensis resembles S. aurita, but pelvic fin with 1 unbranched and 7 branched rays and no black spot on hind part of gill cover, but a faint gold or black area just behind gill opening (Ref. 188). It is distinguished from S. rouxi by having more lower gillrakers, only 30-40 in S. rouxi, and the caudal fin grey, its tips almost black vs. yellow in S. rouxi (Ref. 188).

Forms schools in coastal waters, preferring waters of 24°C. Feeds on a variety of small planktonic invertebrates, fish larvae and phytoplankton. Breeds during the warm season (July-September). Juveniles and adults show clear north-south migrations in the Gabon-Congo-Angola sector of their range and also in the Sierra Leone-Mauritania sector, each area having nurseries. The movements are correlated with the seasonal upwelling. Marketed fresh, frozen or salted.
