Estimates based on models

Preferred temperature (Ref. 115969 ): 12.7 - 26.1, mean 18.6 °C (based on 1171 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.4   ±0.6 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (Fec > 10,000). Vulnerability (Ref. 59153 ):  High vulnerability (64 of 100) . Price category (Ref. 80766 ):   High . Nutrients (Ref. 124155 ):  Calcium = 54.4 [27.0, 99.5] mg/100g ; Iron = 0.537 [0.270, 0.976] mg/100g ; Protein = 19 [17, 21] % ; Omega3 = 0.249 [0.142, 0.421] g/100g ; Selenium = 65 [31, 126] ╬╝g/100g ; VitaminA = 63 [22, 184] ╬╝g/100g ; Zinc = 0.766 [0.459, 1.224] mg/100g (wet weight);
