Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00405 - 0.01357), b=3.11 (2.95 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
