Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 24 - 33; членистые (мягкие) лучи спинного плавника (общее число) : 93 - 143; членистые (мягкие) лучи анального плавника: 90 - 140; позвонки: 95 - 118. Diagnosis: distance from tip of snout to last externally visible dorsal spine relatively short, 43.2-57.9% SL, decreasing with size (Ref. 57415, 81678). Postanal length relatively long, 44.1-58.3, increasing with size (Ref. 57415, 81678), comparable to or longer than preanal length, 40.0-51.8% SL (m=46.6)(Ref. 57415, 81678). Distance from tip of snout to last externally visible anal spine relatively short, 44.3-57.3 SL, decreasing with size (Ref. 57415, 81678). 1st dorsal spine situated clearly posterior to posterior edge of pectoral fin (Ref. 57415), distance from posterior edge of pectoral fin to origin of first dorsal spine 8.9-89.3% HL (Ref. 57415, 81678). Gill opening small, its distance to dorsal pectoral fin base relatively long, 8.3-14.9% HL (mean 11.5%); 23+1 to 32+1 (median 27+1) dorsal spines (Ref. 81678). Distance from anterior border of snout to first anal spine 42.1-53.5% SL (m=48.2), decreasing with size (Ref. 57415).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100).
