Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 13498); common length : 100.0 cm TL male/unsexed; (Ref. 3728)

Facultative air-breathing (Ref. 126274); Found in rivers and lakes. Adults feed on other freshwater fishes and even birds. Young are preyed on by introduced Micropterus salmoides. The flesh is edible; but the eggs are poisonous to eat.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6406 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00229 (0.00091 - 0.00578), b=3.19 (2.97 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.71 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Unknown.
