Estimates based on models

Preferred temperature (Ref. 123201): 11.3 - 13.5, mean 11.8 °C (based on 17 cells).

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

Bayesian length-weight: a=0.00339 (0.00168 - 0.00685), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

營養階層 (Ref. 69278): 3.5 ±0.1 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 (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
