Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00554 - 0.01979), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
營養階層 (Ref. 69278):  2.4   ±0.1 se; based on size and trophs of closest relatives
Generation time: 4.0 ( 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 (tm=2; k=0.27; Tmax=7).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
