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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Generation time: 10.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (tm=3-4; Fec=2 (in captivity)).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Price category (Ref. 80766): Medium.
