Four Methods for Overwintering Rice Field Eels

Technical key points for polyculturing silver and bighead carp in snakehead farming
I. Pond clearing, preparation and disinfection The pond area for polyculturing silver and bighead carp with snakehead is preferably 6-8 mu. If the area is too small, water quality tends to deteriorate easily, and during the main summer period, high-temperature seasons easily trigger disease. If the area is too large, production input is high, and management is inconvenient. The pond water depth should be about 2 m, with no or little bottom mud left. Weeds around the pond must be cleared, and the pond embankments must be tamped and reinforced to prevent seepage and leakage. 20 days before stocking fingerlings, use quicklime to thoroughly clear the pond at 100-150 kg per mu. After 10 days, use bleaching powder (effective chlorine content 30%) to clear the pond once more at 5-7 kg per mu. After one week, water can be added and fingerlings stocked.
