Abstract

BACKGROUND: The induction of triploidy is an effective strategy for the production of sterile fish for aquaculture and has usually been reported to be accompanied by modifications in physiological characteristics. OBJECTIVES: The aim of this study was to assess the effects of triploidy induction on growth performance and amino acid profiles in rainbow trout. METHODS: Eight female (total weight 1600 ± 246 g) and six male (total weight 1393 ± 186 g) four-year-old healthy rainbow trout were used in this study. triploidy was inducted through the application of heat shock of 28 º C for 10 min to eggs 10 min post fertilization in an aquarium equipped with a heater. During the 38 days of rearing period, the fish were fed a rainbow trout commercial diet (BioMar, France) 12 times a day at the rate of 7% of their body weight. Fish ploidy level was determined by erythrocyte size measurement. RESULTS: Based on red blood cell analysis, the overall triploidization success level was 87. 1%. Growth performance was significantly higher in diploids as compared to triploids (p<0. 05). The levels of non essential amino acids increased and the levels of essential amino acids decreased as an effect of triploidy induction. CONCLUSIONS: triploidy induction in rainbow trout affects growth performance and amino acid profiles in rainbow trout.
