Clupeiformes (Herrings) >
Dorosomatidae (Gizzard shads and sardinellas)
Etymology: Amblygaster: Greek, amblys = darkness + Greek, gaster = stomach (Ref. 45335).
More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; pelagic-neritic; depth range 0 - 50 m (Ref. 188). Tropical; 30°N - 23°S, 39°E - 129°E (Ref. 188)
Indo-West Pacific: coasts of Africa eastward to Okinawa, Japan; south to Western Australia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm SL male/unsexed; (Ref. 188); common length : 18.0 cm SL male/unsexed; (Ref. 188)
Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 21; Anal spines: 0; Anal soft rays: 12 - 23. Body moderately slender, 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. clupeoides, which has fewer lower gill rakers.
A schooling species occurring in coastal waters (Ref. 188, 75154).

Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 29.1, mean 28.4 °C (based on 1022 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00227 - 0.01331), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Assuming Fec > 10,000).
Fishing Vulnerability (Ref.
