Abstract
Ultrastructure of spermatozoa produced by artificially induced triploi d Pacific oysters, Crassostrea gigas, was studied by transmission and scanning electron microscopy. Spermatozoa from triploids (3n sperm) re sembled sperm from diploids (2n sperm) and consisted of an acrosome, n ucleus, four mitochondria, and flagellum. The head, acrosome, and flag ellum of 3n sperm were significantly (P< 0.05) larger than those of 2n sperm. The diameter of the mitochondria was not different between 3n and 2n sperm.
