Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

營養階層 (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
