Estimates based on models

Preferred temperature (Ref. 123201): 27 - 29.3, mean 28.7 °C (based on 1511 cells).

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

Bayesian length-weight: a=0.00047 (0.00025 - 0.00089), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Medium.
