Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00661 (0.00409 - 0.01066), b=3.18 (3.04 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.37 se; based on food items. Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (20 of 100).
