Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 41236); common length : 20.0 cm SL male/unsexed; (Ref. 44894)

Facultative air-breathing (Ref. 126274); Adults inhabit both fresh and brackish waters of rivers and swamps (Ref. 2847, 44894) or near the river mouth (Ref. 13533). They occur mainly in thick vegetation of muddy, still water bodies, such as lagoons, swamps, canals and rice fields (Ref. 6028). Live in soft bottom sediments in quiet, well vegetated backwaters of brackish estuaries and nearby swamps (Ref. 44894), usually in burrows. Prefer estuarine or tidal areas, as efficient burrowers. The male guards and builds nest or burrow (Ref. 205). Marketed fresh, usually not kept alive for long periods of time (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00085 (0.00039 - 0.00184), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
