Fusion of lipid droplets in Japanese eel oocytes: Stage classification and its use as a biomarker for induction of final oocyte maturation and ovulation
Abstract The quality of eggs obtained from maturation-induced Japanese eel, Anguilla japonica , is unstable. One of the causes for low quality eggs is that females are artificially induced to ovulateExpand
