Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 14 - 18; членистые (мягкие) лучи анального плавника: 17 - 20; позвонки: 33 - 34. Cynolebias ochraceus can be diagnosed from C. gilbertoi, the only other member of the C. gilbertoi group, by having 33 vertebrae (vs. 31-32), flank light yellow ochre and anal fin orange-yellow ochre in males (vs. flank pale pinkish brown or light brown, anal fin pink or pinkish grey), and tip of anal-fin filaments reaching basal portion of caudal fin in males (vs. reaching posterior half of caudal fin). It can be further distinguished from C. gilbertoi by having 29-31 caudal-fin rays (vs. 26-29) and 9-12 vomerine teeth (vs.11-16), body depth 35.0-37.8% SL in males (vs. 32.5-35.4% SL), and larger maximum adult size (5.7 cm SL vs. 3.7 cm SL) (Ref. 97357).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
