Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.2).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (42 of 100) .
Climate Vulnerability (Ref. 125649
): (0 of 100) .
