Reference (physiological) value intervals determined by the lower 2.5% and upper 97.5% quantiles were calculated for total calcium (Ca t ) and inorganic phosphate (P) in farmed rainbow trout, Oncorhynchus mykiss , at an age of 10–12 months in raceway culture. Total calcium levels were significantly ( P ≤0.0009) greater in males (2.63–4 mmol L −1 , n =47, mean weight 359±142 g) than in immature females (2.48–3.97 mmol L −1 , n =410, mean weight 400±145 g). The reference range for P in immature females and males was 3.09–9.32 mmol L −1 ( n =467, mean weight 401±144 g). The distribution and density of the quantiles in the tested reference group were made possible by the use of histograms, which showed normal distributions for Ca t in males but not for Ca t and P in immature females and males, in which a sinistral asymmetry was found.
