Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Daya lenting (Ref. 120179):  Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
