Estimates based on models
Preferred temperature (Ref.
123201): 8.6 - 12.8, mean 10 °C (based on 7 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.7 ±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 (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
