Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00358 - 0.02119), b=3.14 (2.94 - 3.34), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.34 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (tm<1; multiple spawning per year; Fec=20-150).
Vulnerability (Ref. 59153
): Low vulnerability (19 of 100) .
