Effect of ethanol immersion time on parthenogenesis

The purpose of this research was to investigate the probability of common carp (Cyprinus carpio L.) egg parthenogenesis activated by ethanol. The method used was experimental design, with 7 treatments and 3 replications. The treatment includes positive control ( using sperm) and negative control (without sperm). The immersion times in 7% ethanol were 2; 2.5; 3; 3.5 and 4 minutes. The main parameter was percentage of activated and development egg. The support parameters were temperature, DO, and pH values. The results showed that sperm submerged in ethanol 7% for 2 minutes displayed very significant influence (P<0.05) for activation and development egg with maximum embryo development reached was bastula phase. Water quality data showed that the temperature ranged from 20.1-22.7 degrees C, DO 6.72-6.84, and pH in the range of 7.19-7.55.
