Estimates based on models

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

Bayesian length-weight: a=0.00646 (0.00473 - 0.00882), b=3.05 (2.96 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on diet studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).

Price category (Ref. 80766): Unknown.
