Estimates based on models

Preferred temperature (Ref. 115969): 5.7 - 15.3, mean 9.2 (based on 870 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00141 - 0.00976), b=3.12 (2.89 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.4 se; based on diet studies.

Daya lenting (Ref. 120179): sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (Fec=8).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
