Estimates based on models

Preferred temperature (Ref. 123201): 14 - 27.7, mean 21.8 °C (based on 398 cells).

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

Bayesian length-weight: a=0.00058 (0.00035 - 0.00094), b=3.28 (3.14 - 3.42), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.61 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).

Price category (Ref. 80766): Medium.
