Estimates of some properties based on models

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

Bayesian length-weight: a=0.01479 (0.00693 - 0.03157), b=2.97 (2.80 - 3.14), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.50 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (tm<1; multiple spawning per year).

Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100) .
