Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00310 - 0.01692), b=3.18 (2.98 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (tm=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
