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=0.01023 (0.00598 - 0.01751), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.3 ±0.27 se; based on food items.

Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.35; Fec = 701;).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).
