Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD50 = 1 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00655 - 0.00919), b=3.06 (3.01 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.5 se; Based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.41; tmax=12).

Fishing vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).

Price category (Ref. 80766): Medium; Very questionable: based on ex-vessel price for species in this family.
