Estimates based on models

Preferred temperature (Ref. 123201): 2.2 - 4.9, mean 3 °C (based on 2122 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
