Estimates based on models

Preferred temperature (Ref. 115969): 4.9 - 12.3, mean 8.3 (based on 337 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00204 (0.00113 - 0.00369), b=3.15 (2.99 - 3.31), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 4.4 ±0.4 se; based on diet studies.

Ελαστικότητα (Ref. 120179): Πολύ χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού > 14 έτη (Fec=5).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).
