Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00255 - 0.01297), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=7; Fec=1,742).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (19 of 100).
