Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00223), b=2.98 (2.77 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (K=0.40; tm=3-4).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
