Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00301 (-0.14572 - 0.15174), b=3.15 (3.06 - 3.24), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100) .

Price category (Ref. 80766): .
