Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00562 - 0.01412), b=3.05 (2.92 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.19-0.63(?); tmax=6; Fec > 10,000).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (45 of 100).
