Abstract :

Six induced breeding spawning experiments were conducted on Cyprinus carpio(Linn.) using ovaprim (@0.5ml kg brooder weight )and ovatide (@0.3ml/kg brooder weight) in the modified CIFE-D81 Hatchery Unit of the Thar Desert. The average number of eggs (1.94 lakhs), fertilization rate (56%),hatching rate (70.5%) and spawn production (1.296 lakhs) were obtained after injecting ovaprim. Whereas, ovatide yielded no. of eggs (2.89 lakhs),fertilization rate (88.6%),hatching rate (77.3%) and spawn production (1.941 lakhs).MPOWER (funded by IFAD) project will promote development of small scale freshwater aquaculture in the six district blocks of the Western Rajasthan to alleviate poverty. It will also serve as a tool to benefit large number of rural women involved in various aspects of aquaculture activities and to apply the induced breeding technique to conserve the threatened fish species of the Thar Desert.
