Effect of different levels of selenium nanoparticles on some reproductive indices in rainbow trout (Oncorhynchus mykiss)
Improvement of a diet of rainbow trout (Oncorhynchus mykiss) brooders with selenium nanoparticles has a great effect on reproductive indices. Selenium is very important for male reproduction and its deficiency and low levels can lead to reproductive disorders such as poor fertility and fetal development. In this study, the effects of different levels of selenium nanoparticles on the reproductive performance of rainbow trout male brooders were investigated. 120 four-year-old male fish weighing 2.375kg were selected. After adaptation, the fish were divided into four experimental groups (control, 0.5, 1 and 2 mg selenium nanoparticles per kg diet) with three replications. There was no significant difference in the results of the total length of male brooders. The highest fertilization rate (98.17± 1.60%) was observed in fish fed 2mg nanoselenium which had a significant difference with other treatments. The highest percentage of egg hatching was observed in the broods treated with 2mg/kg nanoselenium (93.93±3.00). The survival rate of offspring showed that with increasing levels of selenium nanoparticles in males, there was an increasing trend in offspring survival. The increasing trend of fertilization and offspring percentages in male brooders fed 2mg selenium nanoparticles had a significant effect on the final results.
