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=0.00955 (0.00430 - 0.02123), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

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).
