Écologie
marin récifal; profondeur 0 - 50 m (Ref. 188). Tropical; 17°N - 19°S, 75°E - 179°W (Ref. 188)
Indo-West Pacific: southern coasts of India, perhaps Bay of Bengal, and Indonesia eastward to Fiji. Reported from New Caledonia (Ref. 9070) and Tonga (Ref. 53797).
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 27.6 cm TL mâle / non sexé; (Ref. 126292); common length : 15.0 cm SL mâle / non sexé; (Ref. 188); poids max. publié: 247.00 g (Ref. 126292)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 13 - 21; Épines anales: 0; Rayons mous anaux: 12 - 23. Body moderately deep, belly rather rounded, scutes not prominent. Distinguished from A. sirm by the absence of spots along the flank (gold in life, black on preservation) and fewer lower gill rakers. Closely resembles A. leiogaster, which has more lower gill rakers. Round-bodied Sardinella species have i 8 pelvic fin rays and more than 100 lower gill rakers.
Forms schools in coastal waters. Feeds on copepods, Mysis and other elements in the zooplankton. Used as bait in the tuna fishery.
