Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 29.1, mean 28 °C (based on 1936 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.04677 (0.01905 - 0.11483), b=2.82 (2.61 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.51 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).

Price category (Ref. 80766): Unknown.
