Potential Cultivation of Koi Fish (Cyprinus Carpio) in Ciliwung River (Segmen Of Rasuna Epicentrum Superblock-Epicentrum River)

The purpose of this research are to understand Koi Fish's (CyprinusCarpio) adaptation ability to Epicentrum river water condition; to determine its adaptation time to Epicentrum river water; to determine the size of Koi fish that most potential to be planted in Epicentrum river; and to determine a simple method that potential for Koi fish cultivation in the Epicentrum river. The research was using quantitative experimental methods, three aquariums size of 100 L completed with water pump, filters, activated carbon, anti-ammonia stones and bio ceramic systems were used in the experiment. The first aquarium is control, the second aquarium (maximum intervention)was intervened with Epicentrum river water, extra filter, treated with pH control and fish medicine, while the third aquarium is only intervened with Epicentrum river water, without extra filter, pH control and medicine (minimum intervention). The result shows that Koi fish can live in Epicentrum river water, but require gradual conditions for Koi fish to get used to the environment; the length of time for adaptation is 3 days; Koi fish that suitable to be planted in the Epicentrum river is 6 cm - 8 cm in size; and Koi fish can live best in condition with minimal intervention.
