Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
Western Indian Ocean: Pondicherry northward along the Coromandel coast, Ganges delta, Myanmar, southward to Malaysia and rarely to the Indonesian Archipelago.
Found in shallow, open muddy bays and estuaries (Ref. 4833). Feed on fish, crustaceans and algae. Spawn twice a year during the months of November to February and August to September and the juveniles migrate toward the upper reaches during March and April and during December where they remain for 2 to 3 months. Sexually mature upon reaching a length of 12 cm (Ref. 6205). Oviparous (Ref. 205).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00395 (-0.17948 - 0.18739), b=3.14 (3.04 - 3.25), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.3 ±0.47 se; Based on food items.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100) .
