Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 13.5, mean 8.5 °C (based on 237 cells).

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

Bayesian length-weight: a=0.00316 (0.00189 - 0.00529), b=3.17 (3.02 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.2 se; based on diet studies.

Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

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

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Climate Vulnerability (Ref. 125649): Low vulnerability (12 of 100).

Nutrients (Ref. 124155): Calcium = 20.6 [11.0, 59.7] mg/100g; Iron = 0.387 [0.145, 1.009] mg/100g; Protein = 11.5 [9.6, 14.7] %; Omega3 = 0.41 [0.16, 1.12] g/100g; Selenium = 26.1 [10.0, 66.7] μg/100g; VitaminA = 12.7 [2.6, 62.0] μg/100g; Zinc = 0.436 [0.272, 0.726] mg/100g (wet weight);
