Estimates based on models

Preferred temperature (Ref. 123201): 4.9 - 8.1, mean 7 °C (based on 26 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

營養階層 (Ref. 69278): 4.0 ±0.4 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 非常低的, 最小族群倍增時間超過14 年 (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
