Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 18 - 23; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 17 - 23; позвонки: 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).

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).
