Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13-21; Anal spines: 0; Anal soft rays: 12 - 23. Diagnosis: Body slender, belly rather rounded, scutes not prominent (Ref. 188). It is distinguished from Amblygaster clupeoides and A. leiogaster by the presence of a series of 10-20 gold, in life, or black, on preservation, spots down the flank, but sometimes missing; also, lower gillrakers 33-43, while 26-33 in the other two species (Ref. 188). Sardinops species are also round-bodied and have spots on the flanks, but possess bony radiating striae on the gill cover; round-bodied Sardinella species have one unbranched and 8 branched pelvic finrays while Amblygaster sirm has one unbranched and 7 branched pelvic finrays, and more than 100 gillrakers are present in Sardinella species, also no spots (Ref. 188). Last 2 anal-fin rays enlarged (Ref. 117228).

Biology     Glossary (e.g. epibenthic)

A pelagic, schooling species occurring in coastal waters and lagoons (Ref. 188, 53568), at depths of 1-75m (Ref. 82332). In Panggang Island, Indonesia it was recorded in temperatures of 28.5-29.8°C and salinities of 31.6-32.3 ppt (Ref. 823). It feeds mainly on copepods, nauplii and zoea larvae, larval bivalves and gastropods, as well as Peridinium and Ceratium; juveniles also on phytoplankton (Ref. 188). Used as bait in the tuna fishery.

Estimates based on models

Preferred temperature (Ref. 115969): 26.2 - 29.1, mean 28.2 °C (based on 1152 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00736 - 0.00984), b=3.04 (3.00 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.30 se; based on food items.
Generation time: 0.9 (0.8 - 1.3) years. Estimated as median ln(3)/K based on 22 growth studies.
