| In trout (Oncorhynchus mykiss) production, differences between tetraploid and diploid gametes have important effects on growth rates and reproductive success. Tetraploidy is a condition in which the chromosome number of individuals is doubled from the diploid level and is generally associated with higher growth rates and superior phenotypic traits. It has been observed that tetraploid individuals have the potential to increase productivity in trout farming because they can produce more eggs and sperm. In addition, the reproductive success rates of tetraploid and diploid individuals were compared in terms of factors such as sperm and egg quality. The genetic and biological advantages of tetraploid individuals were revealed and the potential benefits of these individuals in trout farming were discussed. The findings obtained indicate that the application of tetraploid individuals in trout production may guide future strategies. In this review, the role of tetraploid and diploid gametes in trout production was comprehensively examined. The methods used in the production of tetraploid individuals, especially chemical and physical techniques, were detailed. The effectiveness of these methods and the points to be considered during application were emphasized. |
