Abstract: 

The aim of this study was to assess the effects of triploidy induction on survival, growth performance, body composition and fatty acid profiles in rainbow trout. Eight female (1600±246 g) and 6 male (1393±186 g) of fouryear rainbow trout broodstock were selected and stripped. Heat shock treatment achieved 10 min after fertilization, for 10 min and in 28oC water bath. Based on red blood cell analysis, the overall triploidization success level was 87.1±1%.The survival rate from fertilization to eyed stage in triploid group (86.31±1.21%) was significantly (p<0.05) lower than that of diploid group (92.12±1.59%). The survival rate from eyed stage to hatching in triploids (94.04±1.33%) was significantly (p<0.05) lower than that of diploids (98.10±0.45%). Growth performance (initial and final weight, weight gain, specific growth rate and condition factor) was significantly higher in diploids as compared to triploids (p<0.05) after 38 days of rearing. Proximate compositions of fish including protein, fat and ash were not affected by triploidization, but triploids showed higher moisture content compared to that of the diploids. Moreover, the results showed that the levels of saturated fatty acids increased and the levels of unsaturated fatty acids decreased as an effect of triploidy induction.
