Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 28.7, mean 27.7 °C (based on 632 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00468 - 0.01347), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.16).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
