Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00684 - 0.03200), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.35 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tm<1).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
