Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00393 - 0.01013), b=2.97 (2.83 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.58 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=1-2, Fec>1,000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
Price category (Ref. 80766):   Unknown.
