Etymology: Sardinella: Latin and Greek, sarda = sardine; name related to the island of Sardinia; diminutive (Ref. 45335).

成熟: Lm 19.2  range ? - ? cm
Max length : 27.0 cm TL オス/雌雄の選別がない; (Ref. 103182); common length : 20.0 cm SL オス/雌雄の選別がない; (Ref. 188)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 13 - 21; 肛門の骨: 0; 臀鰭: 12 - 23. Diagnostic features as for Sardinella aurita from which it differs in having the anterior gill rakers on the lower limbs of the second and third gill arches distinctly curled downward (more or less flat in S. aurita) (Ref. 188). The pelvic fin ray count of i 8 distinguishes S. brasiliensis from all other species of Sardinella, also Harengula and Opisthonema (Ref. 188). Similar to S. aurita (Ref. 26938). Bluish black above. Peritoneum black (Ref. 37032). Separation of Sardinella brasiliensis (synonym of Sardinella janeiro) from Sardinella aurita on the basis of gill raker shape and a higher gill raker count is tentative.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found in coastal waters, often forming compact schools. Maximum depth range based on spawners in Brazil (Ref. 114041). Probably similar to S. aurita, but if they are indeed distinct, then this species may account for the double spawning peaks of S. aurita. Constitutes a large fishery in Venezuela, but statistical reports are not separated from S. aurita. Marketed fresh and canned (Ref. 5217).
