What are the four key points to get right in intensive snakehead culture? Detailed techniques
To achieve high yield and good returns in intensive snakehead culture, four key points must be got right. 1. Seed stock: Snakehead is hardy and highly resistant to disease, but during the fry stage the incidence of disease and mortality rate are relatively high. For pond intensive culture, the stocking size of seed stock should be within 100 fish per kg. Such seed stock is close to adult fish in all respects, has a high survival rate after stocking, and is easy to raise. At the same time, note that the seed stock should be uniform in size, free of disease and injury. Deformed fry with a big head and small tail, improper proportions, or protruding eyeballs must not be introduced for stocking.

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.
