Estimates based on models

Preferred temperature (Ref. 123201): 1.2 - 3.8, mean 1.7 °C (based on 95 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00231 - 0.00625), b=3.08 (2.94 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Τροφικό Επίπεδο (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Ελαστικότητα (Ref. 120179):  Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100).
