Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 12; Anale zachte stralen: 7. Oreichthys duospilus is distinguished from its congeners by a combination of the following characters: 22-23+1 scales in the longitudinal series with 11-21 pored scales; ½3/1/2½ scales in the transverse row; 7-9 predorsal scales; two black spots, one on the dorsal fin and the other on the anal fin; and a faint black spot may be seen on the caudal fin base, which may not be consistent (Ref. 99423).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00502 - 0.02287), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
