Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. With 60-65 predorsal scales; without ocellus on caudal peduncle (Ref. 43281).

Facultative air-breathing (Ref. 126274); Found in rivers, swamps, reservoirs and canals. Enters flooded forest (Ref. 9497). Feeds on small fishes, shrimps, aquatic insects, mollusks and crabs (Ref. 6459). Considered a delicacy over much of eastern Asia. Exported fishes command a high price (Ref. 12693). Maybe the largest species of the goby-like fishes.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00512 - 0.01625), b=3.09 (2.93 - 3.25), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.67 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Fec = 10,000).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Price category (Ref. 80766): Unknown.
