Actinopterygii (ray-finned fishes) > Clupeiformes
(Herrings) > Engraulidae
Etymology: Thryssa: Greek, thrissa, -es = shad (Ref. 45335).
Environment / Climate / Range
Marine; brackish; pelagic-neritic; amphidromous (Ref. 51243); depth range 0 - 50 m (Ref. 189). Tropical; 27°N - 7°S, 61°E - 121°E (Ref. 189)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm SL male/unsexed; (Ref. 189)
soft rays: 29 - 37. Belly with 21 to 24 keeled scutes from isthmus to anus. Maxilla very long, reaching at least halfway along pectoral fin and to pelvic fin base in adults; first supra-maxilla absent; lower jaw slender. gill rakers with serrae on the inner edge in distinct clumps. A dark blotch behind upper part of gill opening, sometimes joined to dark saddle on nape.
Indo-Pacific: coasts of Pakistan, India, Myanmar and south of Penang; apparently not yet found in Gulf of Oman or the Persian Gulf; Malaysia, Indonesia north to Taiwan, no records from Papua New Guinea or northern coasts of Australia.
Presumably schooling, mostly inshore and perhaps tolerating estuarine conditions. Feeds on diatoms when young and prawn larvae, copepods and cypris when larger. The number of museum specimens suggest that it is fairly common (but not in Bombay waters).
