Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 8, mean 6 °C (based on 159 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.59 se; based on food items.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (62 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 6.32 [0.98, 112.39] mg/100g; Iron = 0.274 [0.026, 3.186] mg/100g; Protein = 14.7 [13.2, 16.5] %; Omega3 = 0.7 [0.3, 1.8] g/100g; Selenium = 11.4 [2.3, 56.0] μg/100g; VitaminA = 12.9 [1.0, 162.0] μg/100g; Zinc = 0.352 [0.024, 3.890] mg/100g (wet weight); based on nutrient studies.
