Estimates based on models

Preferred temperature (Ref. 123201): 2.7 - 5.5, mean 3.4 °C (based on 43 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00225 - 0.01943), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.49 se; based on food items.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
