Estimates based on models

Preferred temperature (Ref. 123201): 17.8 - 28.2, mean 26.8 °C (based on 434 cells).

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

Bayesian length-weight: a=0.00040 (0.00026 - 0.00060), b=3.21 (3.09 - 3.33), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (64 of 100).

Price category (Ref. 80766): Medium.
