Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 3; Mjukstrålar i ryggfenan (totalt) : 130 - 134; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 98 - 102; Ryggkotor: 165 - 171. Diagnosis: Dorsal fin rays III, 130-134. Pectoral fin rays I, 10; anterior margin of pectoral fin spine not serrate. Anal fin rays I, 98-102; first anal spine base situated below 36th-39th dorsal fin rays. Total vertebrae 165-171; highest point of supraoccipital situated vertically above posterior margin of eye; vertebrae of posterior caudal peduncle bearing neural spines. Spinescent gill rakers with 2 equally long cusps. Horizontal distance between the posterior margin of dermal eye and the origin of the first dorsal spine shorter (73-75% of eye diameter: ED, mean 74%) than eye diameter when viewed laterally. Precaudal peduncle length 82-84% TL; preanal length 25-27% TL; caudal peduncle length 15-17% TL; head length 9% TL; upper jaw length 3-4% TL; predorsal length 6% TL (Ref. 54821).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00191 (0.00078 - 0.00466), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 4.1 ±0.7 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (47 of 100).
