Estimates based on models

Preferred temperature (Ref. 123201): 12.7 - 20.6, mean 16 °C (based on 22 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6252 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.26 se; based on food items.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
