Estimates based on models

Preferred temperature (Ref. 123201): 14.6 - 20.4, mean 20.1 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.7 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): Low to moderate vulnerability (33 of 100).
