Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00397 - 0.01666), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.6 se; based on size and trophs of closest relatives
Generation time: 4.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (tm=5; tmax=12; K=0.23).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (35 of 100) .
Climate Vulnerability (Ref. 125649
