Dorosomatidae (Gizzard shads and sardinellas)
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).

Maturity: Lm 29.0 range ? - ? cm
Max length : 60.0 cm TL เพศผู้/กระเทย; (Ref. 12693); common length : 40.0 cm TL เพศผู้/กระเทย; (Ref. 4832); อายุสูงสุดที่ได้รายงาน: 2.00 ปี (Ref. 26929)
เงี่ยงครีบหลัง (รวม) : 0; เงี่ยงครีบก้น: 0. Belly with 28 to 30 scutes. A distinct median notch in upper jaw, which distinguishes it from other similar clupeids, except Hilsa kelee. Gill rakers fine but not numerous, 60 to 100 on lower part of arch. Caudal fin short. At most, a dark diffuse mark behind gill opening, but no other spots on flank.
Inhabits fast-flowing, turbid estuaries and adjacent coastal waters (Ref. 26929). Schooling in coastal waters, euryhaline and perhaps anadromous, ascending rivers to breed (but in some areas fishery workers claim that it does not). A protandrous hermaphrodite (Ref. 55367). Presumably its biology is similar to that of T. ilisha, but the fewer gill rakers suggest that it takes larger food organisms. Reported to feed on zooplankton (Ref. 58784). More data needed especially since it is not always distinguished from T. ilisha, especially at juvenile stages. Marketed fresh or dried-salted.
Life cycle and mating behavior
Maturities | การสืบพันธุ์ | Spawnings | Egg(s) | Fecundities | ตัวอ่อน
A semelparous species, but although each individual spawns only once and then dies, the spawning season for the species as a whole lasts from May to November (Ref. 26929). A monandric species (Ref. 55367). Sex change occurs at a length of 11.0 cm TL and 1.24 years of age (Ref. 55367).
