Estimates based on models

Preferred temperature (Ref. 123201): 15.6 - 26.5, mean 23.5 °C (based on 180 cells).

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

Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Generation time: 12.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Daya lenting (Ref. 120179): sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (Tm=9-26; Tmax=33).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (79 of 100).

kategori harga (Ref. 80766): Unknown.
