Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7502   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Τροφικό Επίπεδο (Ref. 69278):  3.3   ±0.3 se; based on size and trophs of closest relatives
Ελαστικότητα (Ref. 120179):  Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
