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=0.01820 (0.00845 - 0.03919), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

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

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
