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=0.01148 (0.00624 - 0.02112), b=2.98 (2.82 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.39 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=11).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100).
