Abstract (EN): Growth performance, protein and energy utilization in triploid rainbow trout juveniles of two yearclasses, 0 + and I +, were compared to diploid control groups. Growth rate, food conversion and protein efficiency ratios of triploid rainbow trout did not differ (0 + juveniles) or were slightly lower (1 + juveniles) than the diploid control. Proximate body composition was also not affected by ploidy. Apparentdigestibilitycoefficients (ADC) ofprotein and ofenergy, oxygen uptake, and ammonia excretion rates were not different between the two groups. Nitrogen and energy balance studies showed that digestive and metabolic utilization of the diets did not differ in triploid and diploid rainbow trout juveniles. © 1990 The Fisheries Society of the British Isles.
