Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 26.1, mean 21.8 °C (based on 75 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5029 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00387 - 0.01238), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Price category (Ref. 80766): Unknown.
