Estimates based on models
Preferred temperature (Ref. 115969): 1.3 - 2.8, mean 1.7 (based on 21 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00395 - 0.00554), b=3.24 (3.19 - 3.29), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.5 ±0.52 se; based on food items.
Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.08-0.12; tm=7-9; tmax=19; Fec = >10,000).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).
