Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00354 - 0.01702), b=3.06 (2.89 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 2.7 ±0.1 se; based on size and trophs of closest relatives

Ελαστικότητα (Ref. 120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
