Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. Diagnosis: 42-58 predorsal scales (Ref. 57413, 81660), extending to interorbital space (Ref. 57413). Cheek and opercle scaled (Ref. 81660). Small scales on operculum and preoperculum; 76-86 (perhaps up to 94) scales in longitudinal series (including 4 or more scales on caudal fin); 31-40 scales in rearward transverse series; 1st dorsal fin: VI; 2nd dorsal fin: I,9; anal fin: I,8; pectoral fins: 16 (Ref. 57413, 81660). Caudal fin rounded with 17 segmented rays, 15 of which are branched (Ref. 57413). Coloration: Preserved specimens: dark brown or black, lighter ventrally (Ref. 57413, 81660). Several dark, vertical bars present along midline of flanks, last at base of caudal fin (Ref. 57413). Fins dark; a distinct dark spot on dorsal margin of caudal fin near its base; ventral margins of anal and caudal fins white; pelvics with white lateral margins (Ref. 57413, 81660).

Biology     Glossary (e.g. epibenthic)

Found in estuaries and other brackish-water environments; occasionally entering freshwater (Ref. 57413, 81660). Food items include small crabs (Ref. 10812).

Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 27.9, mean 26.5 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00353 - 0.01295), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Nutrients (Ref. 124155):  Calcium = 224 [121, 457] mg/100g; Iron = 1.05 [0.57, 1.89] mg/100g; Protein = 17.7 [16.0, 19.3] %; Omega3 = 0.149 [0.079, 0.267] g/100g; Selenium = 35.2 [18.0, 71.9] μg/100g; VitaminA = 27.5 [9.8, 66.8] μg/100g; Zinc = 1.84 [1.27, 2.67] mg/100g (wet weight);
