Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00696 - 0.03143), b=2.97 (2.80 - 3.14), in cm total length, 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. 120179
): 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) .
