- Abstract
Amur common carp along with Catla and Rohu was used for study on growth performance under polyculture method. Four locations from Chamarajanagar were selected, which are seasonal water bodies and can retain water for more than 6 months in a year. Fingerlings of uniform size were selected and stocked at the rate of 1 no/m2. Amur common carp showed a better growth and survival rate compared to any other species used for the demonstration and total mean weight of 1395.25 gm was achieved with survival rate of 82%. Catla and Rohu also showed good growth in the seasonal water bodies with 1015.33 and 972.50 gm mean weight respectively for 9 months duration with survival rate of 78 and 62%. Under polyculture method at the end of the demonstration Amur, Catla and Rohu were harvested with 7.4, 3.9 and 3.9 tonnes, respectively. Amur common carp exhibited a better growth and survival rate than any other species in seasonal water bodies, which may be due to the omnivorous feeding habit and resistance to fluctuation to water quality variation.
