Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00162 - 0.00426), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.1 se; based on diet studies.
Generation time: 18.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tm=8-14; Fec=29,000).
Vulnerability (Ref. 59153):  Very high vulnerability (85 of 100) .
Price category (Ref. 80766):   Unknown.
