Estimates based on models

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

Bayesian length-weight: a=0.00708 (0.00594 - 0.00843), b=3.11 (3.06 - 3.16), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.47 se; based on food items.

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 131 [53, 288] mg/100g; Iron = 1.52 [0.82, 3.07] mg/100g; Protein = 16.8 [15.6, 18.2] %; Omega3 = 0.295 [0.126, 0.692] g/100g; Selenium = 77.4 [35.5, 201.7] μg/100g; VitaminA = 29.3 [12.3, 65.9] μg/100g; Zinc = 1.61 [1.15, 2.27] mg/100g (wet weight); based on nutrient studies.
