Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - 70 m (Ref. 54915). Subtropical; 30°S - 37°S, 74°W - 70°W (Ref. 54915)
Southeast Pacific: Coquimbo, Valparaiso and south to Talcahuano, Chile; perhaps reaches further south to Mocha Island, but more southerly records may refer to Sprattus fuegensis. Subspecies have been noted (Ref. 6698): Strangomera bentincki bentincki (Talcahuano southward) and Strangomera bentincki cuga (Valparaiso to Talcahuano).
Length at first maturity / Size / Weight / Age
Maturity: Lm 10.5, range 10 - 11 cm
Max length : 28.4 cm SL male/unsexed; (Ref. 27363)
Occurs in schools at or near the surface in coastal waters. Feeds on plankton, especially diatoms (filter-feeding). Breeds mainly from June to November, from a length of about 10 cm. Eggs and larvae are planktonic (Ref. 52017). Mainly used for fishmeal.
Apparently releases planktonic eggs (similar to the demersal eggs of northern hemisphere Clupea).
