Live sperm from post-mortem preserved Indian catfish

In the 240-day post-mortem preserved (at -20°C) specimens of Heteropneustes fossilis, live, fertile sperm are present. Motility and initiation of development were adduced as evidence for survival and fertility of the cadaveric sperm. Of the normal eggs that were fertilized by the cadaveric sperm, 97...

Description
Summary:In the 240-day post-mortem preserved (at -20°C) specimens of Heteropneustes fossilis, live, fertile sperm are present. Motility and initiation of development were adduced as evidence for survival and fertility of the cadaveric sperm. Of the normal eggs that were fertilized by the cadaveric sperm, 97% underwent cortical reactions, 95% first few cell divisions, 40% blastulation, 3% gastrulation and 2% alone successfully hatched.
