Issue
Chionodraco kathleenae Regan, 1914 is considered as valid by ECoF but no taxaonomic evidence is provided since Iwami & Kock (1990) who synonymized the species..

Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - 0.5, mean -1.1 °C (based on 374 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00105 (0.00065 - 0.00167), b=3.52 (3.38 - 3.66), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.53 se; based on food items.
Generation time: 9.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 2,510-4,571).
Fishing Vulnerability (Ref. 59153):  High vulnerability (61 of 100).
Climate Vulnerability (Ref. 125649):  High vulnerability (65 of 100).
Nutrients (Ref. 124155):  Calcium = 25.9 [14.2, 59.5] mg/100g; Iron = 0.427 [0.177, 0.869] mg/100g; Protein = 17.2 [15.5, 18.9] %; Omega3 = 0.231 [0.120, 0.446] g/100g; Selenium = 18.7 [7.5, 43.9] μg/100g; VitaminA = 18.1 [3.8, 88.5] μg/100g; Zinc = 0.426 [0.270, 0.656] mg/100g (wet weight);
