Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00250 - 0.00959), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±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 (35 of 100).

Price category (Ref. 80766): Medium.
