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=0.01047 (0.00646 - 0.01697), b=2.97 (2.84 - 3.10), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.9   ±0.4 se; based on diet studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; K=0.23-0.28; Min batch fecundity >10,000).
Rate of population increase Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 1 data-limited stock assessment.
