Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00582 - 0.01642), b=3.13 (2.99 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

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 (27 of 100).

Price category (Ref. 80766): Unknown.
