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=0.01950 (0.01562 - 0.02435), b=3.01 (2.96 - 3.06), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.26 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=600-800).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
Nutrients (Ref. 124155):  Calcium = 178 [92, 341] mg/100g ; Iron = 1.25 [0.76, 2.46] mg/100g ; Protein = 17.3 [15.9, 18.7] % ; Omega3 = 0.492 [0.222, 1.158] g/100g ; Selenium = 52.6 [25.6, 106.7] μg/100g ; VitaminA = 26.5 [6.5, 82.1] μg/100g ; Zinc = 2.2 [1.4, 3.9] mg/100g (wet weight);
