Diploid, triploid and tetraploid males of silver crucian carp, Carassius auratus, produced live motile spermatozoa, capable of fertilization. Flow cytometry for the relative DNA content in male gametes revealed spermatozoa of diploid males to be haploid, those of triploid males to be aneuploid and those of tetraploid male to be aneuploid and/or diploid. Concentration of spermatozoa and the percentage of live spermatozoa showed a tendency to drop with increasing ploidy level and this effect was significant for the tetraploid male compared to those of lower ploidy levels.
