Estimates based on models

Preferred temperature (Ref. 123201 ): 24.2 - 28.6, mean 27.2 °C (based on 30 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00110 (0.00044 - 0.00274), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.0   ±0.7 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (44 of 100). Nutrients (Ref. 124155 ):  Calcium = 122 [71, 228] mg/100g; Iron = 1.14 [0.68, 1.87] mg/100g; Protein = 17.8 [14.9, 20.7] %; Omega3 = 0.182 [0.082, 0.488] g/100g; Selenium = 62.5 [32.0, 133.1] μg/100g; VitaminA = 25.9 [7.8, 84.9] μg/100g; Zinc = 0.911 [0.656, 1.277] mg/100g (wet weight);
