Etymology: Thryssa: Greek, thrissa, -es = shad (Ref. 45335).
Environment / Climate / Range
Marine; brackish; reef-associated; depth range 0 - 50 m (Ref. 189). Tropical, preferred ?; 31°N - 25°S, 30°E - 172°W (Ref. 189)
Indo-Pacific: Red Sea to Mozambique, Madagascar and Mauritius, east to Samoa, north to the Philippine, Caroline and Mariana islands. The Ogasawara (Bonin) record seems reliable. No Indian specimens. Probably occurs in the Persian Gulf. Occurrence in Thailand (Ref. 1632) needs to be confirmed.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm SL male/unsexed; (Ref. 54980); common length : 10.0 cm TL male/unsexed; (Ref. 5450)
soft rays: 27 - 30. Belly rounded before pelvic fins, with 4 to 9 + 7 to 10 = 12 to 18 keeled scutes, the pre-pelvic scutes ending below the pectoral fin base or behind it. Maxilla short, reaching to just beyond front border of pre-operculum, tip pointed.
Found mostly in inshore bays, lagoons, harbors, mangrove pools and estuaries, thus apparently able to tolerate lowered salinities. Inhabits turbid waters, forming large schools (Ref. 1602). Also caught using ringnets (Ref. 5213). Used as tuna baitfish.
