Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - 50 m (Ref. 188). Tropical; 33°N - 5°S, 116°W - 77°W (Ref. 188)
Eastern Pacific: Gulf of California to the Gulf of Guayaquil.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm SL male/unsexed; (Ref. 188); common length : 10.0 cm SL male/unsexed; (Ref. 188)
soft rays: 12 - 23. Body moderately slender, quite strongly compressed, belly sharply keeled. The bright silver stripe along the flank distinguishes it from all similar clupeids in the area. Hind border of gill opening evenly rounded (with two fleshy outgrowths in Harengula and Opisthonema, the latter with a filamentous last dorsal fin ray).
A coastal-pelagic species that forms dense schools in beaches, lagoons and estuaries (Ref. 9291). Tolerates brackish and fresh waters (Ref. 9291). Feeds on plankton, especially on small crustaceans and fish larvae (Ref. 9291). Processed into oil and fishmeal (Ref. 37955).

Preferred temperature (Ref. 115969
): 20.6 - 28.5, mean 25.6 °C (based on 58 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00629 - 0.01666), b=3.07 (2.93 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.43 se; based on food items.
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=1.36).
Vulnerability (Ref. 59153
