Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00283 - 0.01223), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Generation time: 2.0 ( 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; Fec = 5,370).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
