Temperature is one of the factors that can affect the maturity of the gonads in fish. This study aims to find out what is the best temperature for maturation of broodstock to prepare G5 transgenic mutiara catfish broodstock that are ready to hatch based on gonado somatic index (G...
In the case of common carp (Cyprinus carpio) and goldfish (Carrasius auratus) that were lightly infected with Koi Herpes Virus (KHV), the use of the one-step PCR method was insensitive to detect the presence of KHV DNA. The nested PCR method has been developed for a more sensitiv...
