Studies on the pathogenicity of selected major Carpsat Bansagar colony pond, Rewa (M.P.)
Sheela Saket, Dr. Umesh Pandey
This study examined the pathogenicity of selected major carps at Bansagar colony pond, Rewa (M.P.). For treatment, the diseased fish were exposed to 4g salt per litre of water for 2 min accompanied by way of dip treatment with 5ppm KMnO4 for 10 min, thrice every week for a duration of 6 weeks. The treatment resulted in recuperation from the sickness after 6 weeks from the establishing of treatment. Soon after recovery, the pond administration practices such as removal of pond bottom soil, application of lime and replenishment with freshwater had been followed in the contaminated ponds. Our study concluded that rapid decrease in pond water temperature from 22 to 8°C that stays low for months collectively coupled with increased water pH (8) and decrease dissolved oxygen (4ppm) causes saprolegniasis to the fingerlings of major carps.
