Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.37 se; based on food items.
Generation time: 4.4 ( 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; Fec=40; K=0.3).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100).
