Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.01596 - 0.02274), b=2.97 (2.92 - 3.02), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.2 ±0.12 se; based on food items.
Daya lenting (Ref.
120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.19-0.43; Tmax=5).
Fishing Vulnerability (Ref.
