Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 26.3, mean 25.3 °C (based on 11 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01778 (0.00976 - 0.03241), b=3.03 (2.88 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 18 [8, 28] mg/100g; Iron = 0.516 [0.257, 1.003] mg/100g; Protein = 20.6 [19.5, 21.8] %; Omega3 = 0.224 [0.129, 0.400] g/100g; Selenium = 18.1 [8.4, 37.2] μg/100g; VitaminA = 63.5 [19.0, 207.2] μg/100g; Zinc = 0.509 [0.332, 0.761] mg/100g (wet weight);
