Indo-West Pacific: ranges from Pakistan eastwards to Thailand and southwards to Indonesia and Polynesia. Known from the Mekong delta (Ref. 12693).

Length at first maturity / Taille / Poids / Âge

Maturity: L_m ?, range 24 - ? cm
Max length : 92.0 cm TL mâle / non sexé; (Ref. 3290); common length : 55.0 cm TL mâle / non sexé; (Ref. 3290); âge max. reporté: 6 années (Ref. 52060)

Inhabits coastal waters, as well as estuaries and tidal rivers. Feeds mainly on invertebrates and small fishes. The sharp dorsal and pectoral fin spines can inflict painful wounds. Sold mostly fresh and dried-salted in markets.

Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 28.1, mean 27.3 °C (based on 111 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00458 - 0.01258), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.61 se; based on food items.

Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.36; tm=2; tmax=6).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).

Catégorie de prix (Ref. 80766): Medium.
