Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00164 - 0.00402), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.6 se; based on size and trophs of closest relatives
Daya lenting (Ref.
120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (72 of 100).
