Triploid rainbow trout identified by flow cytometry

Spontaneous and induced triploid rainbow trout were identified by analysis of the DNA content of red blood cells with flow cytometry. Two spontaneous triploids were found among 30 adult trout that failed to mature in a hatchery at 2 years of age. Fifteen induced triploids were recognized among fish...

Summary:Spontaneous and induced triploid rainbow trout were identified by analysis of the DNA content of red blood cells with flow cytometry. Two spontaneous triploids were found among 30 adult trout that failed to mature in a hatchery at 2 years of age. Fifteen induced triploids were recognized among fish previously treated as fertilized eggs with heat shocks to induce polyploidy. There was no evidence of diploid cells in the triploid individuals. Flow cytometry should be a useful technique for identifying polyploid individuals in future studies.
