Abstract: The aim of the study was to observe the influence of different ploidy levels in fish on micronucleus occur­rence. Twenty minutes after fertilization, one group of rainbow trout eggs was exposed to water temperatures of 26°C in duration of 20 minutes to induce triploidy. Second group was kept in water temperature of 10°C, which is optimal for development of rainbow trout. The frequency of micronucleated erythrocytes was determined in the peripheral circulation of rainbow trout 67 days (following absorption of the yolk - swim-up stage) and 128 days (fry stage) post fertilization. There was a significant difference (P < 0.001) between frequency of micronucleated erythrocytes of diploid (1.10 ± 0.96‰) and triploid (2.41 ± 1.28‰) fish at swim-up stage. Increased mean values of micronucleus in diploid (1.80 ± 1.57‰) and triploid (5.92 ± 3.80‰) fry were also recorded.
