This study was aimed at construction of reference (physiological) value intervals determined by lower 2.5% and upper 97.5% quantiles for total plasma protein (TPP) in farmed rainbow trout, Oncorhychus mykiss (Kamloops strain), aged 10–12 months ( n= 755). Total plasma protein in male trout from raceway culture was found to be significantly greater (38–58.3 g L −1 ) relative to females (31–51.5 g L −1 ). Total plasma protein in trout from cage culture was significantly greater (32–54 g L −1 ) compared with the raceway culture (31–49 g L −1 ). Moderate product–moment correlations between TPP and cholesterol ( r =0.8730), TPP and total calcium ( r =0.8188), TPP and alanine aminotransferase ( r =0.6200) and between TPP and aspartate aminotransferase ( r =0.6430) were estimated. Proteinaemia was explained as a metabolic response to feed content, infections of bacterial or viral aetiology or to intoxications.
