Performance of dual culture of Amur Carp and Jayanti Rohu in Imphal East district, Manipur

Adual culture of Amur common carp and Jayanti rohu were demonstrated for the first time in Imphal East district, Manipur. The trial was conducted in five farmers ponds of a total 2 ha area for eight months period. Conventional feed like mustard oil cake (MOC) and rice bran (RB) @ 1:1 ratio was fed to the fish @ 3-6 percent of body weight per day in two installments by the farmers. Water quality parameters and plankton analysis were done during the culture period. Water temperature was found in the range of 20.4 to 27.7°C, pH was maintained in the optimum range of 7.2 to 7.6 and plankton analysis appeared between 0.4 to 6.3 mg/l. After eight months of the culture period, the average body weight (standard length) of Amur carp and Jayanti rohu were recorded as 751 g (20.46 cm) and 562.5 g (19.72 cm), respectively.
