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 (0.00160 - 0.00413), 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): 3.3 ±0.1 se; based on diet studies.
Generation time: 22.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Daya lenting (Ref.
120179): sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (tm=8-14; tmax=65; Fec=29,000).
Fishing Vulnerability (Ref.
