Estimates based on models

Preferred temperature (Ref. 123201): 9.2 - 17.8, mean 12.6 °C (based on 332 cells).

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

Bayesian length-weight: a=0.01380 (0.00744 - 0.02562), b=3.06 (2.90 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
