Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00049 (-0.17502 - 0.17600), b=3.13538 (3.03821 - 3.23256), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.0 ±0.7 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100) .

Price category (Ref. 80766): Medium.
