Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00450 - 0.02327), b=3.11 (2.92 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Assuming tm < 1).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
