Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01903 - 0.03635), b=3.05 (2.96 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.57 se; based on food items.
Generation time: 6.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.16-0.20; tmax=7; Fec=2,085-6,615).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (44 of 100) .
Climate Vulnerability (Ref. 125649
): (0 of 100) .
