Längd vid första mognad / Storlek / Vikt / Ålder
Könsmognad: Lm 22.0, range 18 - ? cm
Max length : 40.0 cm TL hane/ej könsbestämd; (Ref. 3722); common length : 30.0 cm TL hane/ej könsbestämd; (Ref. 3722); publicerad maxvikt: 1.0 kg (Ref. 4699)
Adults inhabit shallow coastal waters and common in brackish waters (Ref. 36880), mostly over mud bottoms in mangrove-lined creeks and lagoons (Ref. 3722); often entering a considerable distance into freshwaters (Ref. 36880). They feed on aquatic insects, crustaceans, micro-bivalves and detritus (Ref. 36880). Marketed fresh; processed into fishmeal (Ref. 3722).
