Eggs of normal diploid (2n) Loach were fertilized with spermatozoa of induced triploid (3n) Loach. The resultant 2n × 3n progeny showed lower survival and higher incidence of abnormality in larval stage than the control 2n × 2n cross, but a small number of individuals survived. Chromosome observation showed hyperdiploidy of the 2n × 3n fry. DNA content of the two-month-old survivors measured by flow cytometry showed that they were viable 2.2 to 2.5n aneuploids.
