Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12000 (3.03000 - 3.21000), based on all LWR estimates for this BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.4 ±0.45 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months ().

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .

Price category (Ref. 80766): Unknown.
