Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00654 - 0.02211), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.7 se; based on size and trophs of closest relatives
Generation time: 3.0 ( 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 (tmax=6).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100).
