Etymology: Tenualosa: Latin, tenuis = thin + Latin, alausa = a fish cited by Ausonius and Latin, halec = pickle, dealing with the Greek word hals = salt; it is also the old Saxon name for shad = "alli" ; 1591 (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; pelagic-neritic; anadromous (Ref. 51243); depth range 0 - 50 m (Ref. 188). Tropical; 7°N - 9°S, 101°E - 119°E (Ref. 188)
Western Central Pacific: Malaysia, Indonesia (Java Sea and Sarawak, also affluent rivers) and Thailand (southern tip).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 52.0 cm SL male/unsexed; (Ref. 188)
spines: 0. Body moderately deep, belly with 30 to 31 scutes. A median notch on upper jaw distinguishes it from other similar clupeids, except Hilsa kelee. Gill rakers fine but not numerous. Caudal fin long, the lobes long and pointed. No series of dark spots along flank. Resembles T. toli, which has longer head but shorter tail; T. reevesii has many more lower gill rakers and a larger head.
Schooling in coastal waters and ascending rivers to breed. Feeds on zooplankton (Ref. 58784). Presumably its biology is similar to that of T. ilisha, but the fewer gillrakers suggest that it takes larger food organisms. A protandrous hermaphrodite (Ref. 55367).
