Short description Morfologia | Morfometria

Spine dorsali (totale): 10 - 12; Raggi dorsali molli (totale): 24-28; Spine anali 2; Raggi anali molli: 7 - 8. This species is distinguished from other species of the subgenus J. (Johnieops) by lacking an enlarged outer row teeth on the upper jaw; unique body color pattern of a grayish dorsal part divided by a distinct line from the whitish ventral one third; with a black dot on uppermost axilla of pectoral fin (vs. absent in other congeners except J. carouna); second anal-fin spine less than 30% of head length (vs. 35% in J. carouna); with cavernous but firm head and firmly attached scales (vs. head strongly cavernous and soft, and the scales on the body fall off easily in J. trewavasae, also with very short, tubercle-like gill rakers and a thicker second anal-fin spine); produces a sound that is unique amongst sciaenids in the coastal waters of Taiwan (Ref. 121822).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00410 - 0.01937), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
