Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 21 - 24; Anal spines: 2; Anal soft rays: 10 - 12. Colour greyish above, whitish below. Dorsal fin dusky, upper margin of pectoral fins orange, pelvic fins and anal fin pale, caudal fin grey with a dark margin. Inside of mouth orange. Mouth large, distinctly oblique, lower jaw projecting. Tip of upper jaw without enlarged canines. Chin without barbels or pores. Snout with only 2 marginal pores. Pectoral fins much shorter than pelvic fins. Gas bladder with a pair of medium-sized, nearly straight, horn-like anterior appendages. Soft portion of dorsal fin almost entirely covered with small scales (Ref 51721).

Biology     Glossary (e.g. epibenthic)

Mostly in brackish water swamps along the coasts; also entering freshwaters (Ref. 3702). Feeds on fish, shrimps and sometimes plants (Ref. 35237). Spawning takes place in the open sea. Important food fish (Ref. 3702).

Estimates based on models

Preferred temperature (Ref. 123201): 26.7 - 28.4, mean 27.7 °C (based on 103 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00386 - 0.01791), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.53 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 79.6 [48.9, 162.6] mg/100g; Iron = 0.858 [0.433, 1.558] mg/100g; Protein = 18.4 [16.8, 20.1] %; Omega3 = 0.159 [0.082, 0.271] g/100g; Selenium = 44.7 [24.9, 91.1] μg/100g; VitaminA = 12.5 [4.7, 33.4] μg/100g; Zinc = 1.17 [0.84, 1.68] mg/100g (wet weight);
