Estimates based on models
Preferred temperature (Ref. 115969): 11.3 - 21.8, mean 19.5 (based on 65 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00264 - 0.00601), b=3.02 (2.90 - 3.14), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
營養階層 (Ref. 69278): 3.7 ±0.55 se; based on food items.
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): Very high vulnerability (90 of 100).
