Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 24.6, mean 23.7 °C (based on 18 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Nutrients (Ref. 124155): Calcium = 57.5 [23.8, 122.0] mg/100g; Iron = 0.667 [0.336, 1.265] mg/100g; Protein = 18.6 [16.6, 20.4] %; Omega3 = 0.0776 [, ] g/100g; Selenium = 26.4 [13.4, 55.0] μg/100g; VitaminA = 137 [49, 398] μg/100g; Zinc = 1.28 [0.82, 2.01] mg/100g (wet weight);
