Koi (Cyprinus rubrofuscus) is one of the ornamental fish that is popular in Indonesia and currently cultivated for business. Koi breeders can reduce production costs by identifying the sex of koi earlier with molecular method (molecular fish sexing) to get accurate result. Routine hematology examination is important to evaluate the health condition of koi. This study aims to determine the sex of the Shiro Bekko koi using the PCR method and to determine the blood profile of ten Shiro Bekko koi, which were kept in an aquarium for three days.
Deoxyribonucleic Acid (DNA) were extracted from blood samples taken from the caudal veins of ten Shiro Bekko koi (which had previously been anesthetized with Koi Anesthesia) using the gSYNC™ DNA Extraction Kit. The sex of the koi was identified by amplifying the sex-specific marker sequence in the koi DNA, which had been successfully extracted, using the primer ArS-9-15 by PCR method. PCR results were electrophoresed with 1.5% agarose gel and FloroSafe gel stain. The result of DNA electrophoresis was visualized using a UV transilluminator with a wavelength of 280 nm and showed the presence of DNA bands of 850 bp and 1,100 bp in male fish and a single DNA band of 800 bp in female fish. The results of molecular fish sexing of ten Shiro Bekko koi fish showed that 80% of them were male and 20% were female. The results of the hematological examination of Shiro Bekko showed differences with the range of values in the reference due to differences in age, body size, and environmental conditions where the fishes live.
