Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 10 - 12; Rückenflossenweichstrahlen (insgesamt) : 27 - 32; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 7 - 8. Snout rounded but not swollen or projecting; mouth large, oblique; upper jaw extending backward below posterior half of eye; no barbel on chin; teeth in narrow bands, well differentiated into large and small in both jaws, but none canine-like; gill rakers slender, about half length of gill filaments at angle of arch, 9 to 15 on lower limb. Second anal spine moderately long, 24 to 42 % of head length. Scales on head cycloid (smooth). Swim bladder hammer-shaped, the first pair of arborescent appendages entering head beyond transverse septum and sending a palmate branch to the front of pectoral arch. Sagitta (large earstone) with a tadpole-shaped impression, the head of which has its long axis lying obliquely to that of sagitta and the tail expanded and deepened as a hallow cone connected with the head by narrow groove.
Inhabits shallow coastal waters, estuaries, and rivers. In India, matures at the size of 14 to 16 cm TL; attains an average size of 15.8 cm TL, 20.6 cm TL, and 24 cm TL, at the end of 1 year, 1.5 years and 2 years, respectively. Juveniles prefer crustaceans and as they grow , show piscivorous tendency (Ref. 9772). Marketed fresh and dried salted (Ref. 3490).

Estimates based on models
Preferred temperature (Ref. 115969): 24.6 - 29.1, mean 28 (based on 2424 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00326 - 0.00737), b=3.12 (3.00 - 3.24), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.7 ±0.4 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=0.5-0.8).
Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
