Estimates based on models

Preferred temperature (Ref. 115969): 26.1 - 28.9, mean 27.8 °C (based on 300 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00261 - 0.01268), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
脆弱性 (Ref. 59153):  Low vulnerability (10 of 100) .
Nutrients (Ref. 124155):  Calcium = 272 [100, 749] mg/100g ; Iron = 1.69 [0.80, 3.84] mg/100g ; Protein = 18.5 [16.5, 20.4] % ; Omega3 = 0.204 [0.084, 0.507] g/100g ; Selenium = 9.49 [3.29, 26.66] μg/100g ; VitaminA = 114 [24, 528] μg/100g ; Zinc = 2.26 [1.18, 4.31] mg/100g (wet weight);
