Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 10-12; Anal spines: 3; Anal soft rays: 11 - 12. Preorbital serrae 18-28; a few fine serrae may be present on suborbital; body depth 2.7-3.05 in SL; orbit diameter 2.75-3.3 in head length; maxilla extending to or slightly beyond a vertical at front edge of pupil; caudal concavity 2.5-3.1 in head length. Silvery, usually with blackish spots posteriorly on dorsal part of body that tends to merge to form bands anteriorly (or the dark pigment is concentrated on scale margins); most of snout and tip of chin blackish; caudal fin pale with a black posterior margin that broadens on lobe tips, then a very broad submarginal pale zone, often preceded by a chevron-shaped blackish band or row of blackish spots parallel with posterior margin; base of caudal fin with small blackish spots; a narrow white margin on soft portion of dorsal and anal fins with a broad blackish submarginal zone anteriorly that narrows posteriorly (broader in dorsal fin than anal) (Ref. 41640).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Asia and Oceania: Taiwan, Philippines and Indonesia to islands in the Pacific. The name Kuhlia marginata has been misapplied to other species and therefore some literature records may be suspect (Ref. 41640).

Biology     Glossary (e.g. epibenthic)

Primarily a freshwater species; extent of penetration into brackish and marine environments uncertain (Ref. 41640). Has been found in moderately deep (1.5-3 m), rocky, unshaded, flowing water areas of mid-hill rivers (Ref. 6028).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01200 (0.00487 - 0.02959), b=3.06 (2.84 - 3.28), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100) .
Price category (Ref. 80766):   Unknown.
