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=0.01905 (0.00999 - 0.03633), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100).

Price category (Ref. 80766): Unknown.
