Etymology: Thryssa: Greek, thrissa, -es = shad (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic. Subtropical; 31°N - 24°N, 46°E - 58°E (Ref. 189)
Western Indian Ocean: known only from the Persian Gulf, but perhaps reaches into the Gulf of Oman.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.8 cm SL male/unsexed; (Ref. 189)
soft rays: 40 - 43. Belly with 25 to 27 (rarely 28) keeled scutes from isthmus to anus. Tip of snout above level of eye center, usually about level of upper rim of eye. Maxilla moderate, its tip projecting just a little beyond edge of gill cover; first supra-maxilla absent; jaw teeth slightly enlarged compared with other species. Blotch behind upper part of gill opening absent or very indistinct.
Pelagic (Ref. 68964). Presumably schooling. More data needed. Apparently common but seldom seen in the market at Kuwait.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00183 - 0.00997), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
