Estimates based on models

Preferred temperature (Ref. 123201): 9 - 16.9, mean 12.8 °C (based on 23 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
