Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00248 - 0.01216), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.2 se; based on size and trophs of closest relatives

Generation time: 5.6 ( 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=0.19-0.29).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).

Price category (Ref. 80766): Unknown.
