Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00269 (0.00166 - 0.00436), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for species & Genus-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.1 se; based on diet studies.

Generation time: 22.0 ( 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। (tm=8-14; Fec=29,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (87 of 100) .

Climate Vulnerability (Ref. 125649): (0 of 100) .

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 15.7 [7.7, 30.8] mg/100g ; Iron = 0.227 [0.138, 0.386] mg/100g ; Protein = 16.6 [13.9, 19.4] % ; Omega3 = 0.672 [0.327, 1.397] g/100g ; Selenium = 32.1 [15.0, 81.7] μg/100g ; VitaminA = 6 [2, 19] μg/100g ; Zinc = 0.481 [0.312, 0.760] mg/100g (wet weight);
