Estimates based on models

Preferred temperature (Ref. 115969): 2.9 - 19.2, mean 6.9 (based on 5921 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00288 (0.00166 - 0.00500), b=3.03 (2.87 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.3 ±0.40 se; based on food items.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
