Eastern Pacific: Santa Rosalita, Pacific coast of Baja, California, Mexico southward to Punta Sal and Punta Picos, Peru. (Earlier works probably combined data for Opisthonema bulleri and Opisthonema medirastre). Range is extended northwards to San Pedro, California (Ref. 35601). Rare on outer coast of Baja California Sur (Ref. 35601).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 21; Anal spines: 0; Anal soft rays: 12 - 23. The filamentous last dorsal fin ray distinguishes it from members of any other eastern Pacific clupeoid genus. Separated from eastern Pacific Opisthonema species by having 63 to 110 lower gill rakers in fishes over 14 cm standard length.

Usually occur near the surface of coastal and offshore waters, down to over bottom of continental shelf (Ref. 11035). Form dense schools. Apparently the most abundant of the eastern Pacific species of Opisthonema. Feed on phytoplankton (dinoflagellates and diatoms). Oviparous, with planktonic eggs and larvae (Ref. 35601). It is reduced to fish meal (Ref. 9291). Oil may be extracted (Ref. 9291). May be canned (Ref. 9291).

Estimates based on models

Preferred temperature (Ref. 115969): 21.4 - 29, mean 27 (based on 86 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00504 - 0.01373), b=3.02 (2.88 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.28 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.22-0.5).

Prior r = 0.43, 95% CL = 0.28 - 0.64, Based on 2 full stock assessments.

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (37 of 100).

Price category (Ref. 80766): Medium.
