Effect of Temperatures and Storage Periods on Fertilizing and Hatching of Short-Term Preserved Scaly Carp (Cyprinus carpio) Eggs

Preserved fish eggs can be used in many applications including artificial propagation and genetic studies. The aim of this study was to determine the effects of different temperatures and storage periods on fertilization and hatching success of short-term preserved scaly carp (Cyprinus carpio) eggs. Eggs were kept in 4 ml ovarian fluid in 10-cm petri dishes that were stored in a refrigerator at 4°C, 8°C, or 12oC for 30, 60, or 90 min. The stored eggs were fertilized by adding 200 μl milt to each petri dish. The highest fertilization (98%) and hatching (80%) rates were obtained with eggs stored for 30 min at 8oC and 12oC respectively, indicating that this combination was best for short-term preservation of scaly carp eggs.
