Abstract
The purpose of this research was to investigate the probability of common carp (Cyprinus carpía 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°C, DO 6.72-6.84, and pH in the range of 7.19-7.55.
