Estimates based on models

Preferred temperature (Ref. 123201): 25.9 - 29.3, mean 27.8 °C (based on 498 cells).

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

Bayesian length-weight: a=0.00933 (0.00596 - 0.01462), b=3.06 (2.93 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.61 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.44-0.73; tm=1.4).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (25 of 100).

Price category (Ref. 80766): Medium.
