Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 14, mean 5.7 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5159 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00200 - 0.01144), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.3 se; based on diet studies.

Generation time: 3.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 48.2 [20.2, 104.8] mg/100g; Iron = 0.442 [0.199, 0.920] mg/100g; Protein = 17.7 [15.7, 19.7] %; Omega3 = 0.567 [0.256, 1.561] g/100g; Selenium = 18.4 [9.3, 43.0] μg/100g; VitaminA = 16.1 [4.9, 53.8] μg/100g; Zinc = 0.461 [0.309, 0.704] mg/100g (wet weight);
