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=0.00977 (0.00802 - 0.01191), b=2.94 (2.90 - 2.98), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100).
