Estimates based on models

Preferred temperature (Ref. 123201): 18.5 - 28.9, mean 25.8 °C (based on 82 cells).

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

Bayesian length-weight: a=0.01259 (0.00719 - 0.02203), b=2.90 (2.74 - 3.06), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.18 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100).
