Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 9.4, mean 6.1 °C (based on 78 cells).

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

Bayesian length-weight: a=0.01023 (0.00426 - 0.02456), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

营养阶层 (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

回复力 (Ref. 120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).
