1. Thorough disinfection of clear ponds and one application of base fertilizer
In front of the fish ponds, dredging and drainage channels must be cleared to remove excess silt from the ponds. When the water depth is 20 centimeters, 100 kilograms of quicklime per mu of fish ponds are used to disinfect water, kill pests, germs, and microorganisms, and 500 kg of decomposed human and animal manure is used as base fertilizer. Then the water depth was 2 to 2.5 meters. After 1 week, the drug disappeared and the fish was released.
2, increase stocking specifications, put "two fish species"
Large-sized fingerlings have a high survival rate, a large absolute increase, and they can ensure that the product specifications for the ponds are captured. Therefore, the stocking specifications are preferably 200 to 400 grams of grass carp, 100 to 300 grams of carp, and 50 to 150 grams of carp.
3, a reasonable mix of polyculture, the implementation of three-dimensional fish
In order to make full use of the water space and natural food, we must use the three-dimensional culture of squid, tilapia, tilapia, and other “fish and fish†and grass, oysters, squid and other “eating fishâ€. Each acre stocking "two fish species" 1200 ~ 1500 tails, which accounted for 40% of grass carp, quail accounted for 40%, oysters, oysters, clams, tilapia 20%, total stocking capacity of 150 kg per mu.
4, feeding compound feed, adhere to intensive fine tube
According to the physiology and life requirements of fish, wheat bran, rice bran, bean cake flour, distiller's grains, minerals, vitamins and fish medicines are used to prepare the mixed (mixed) feed and improve the efficiency of feeding. Each year, it feeds 1500 kilograms per mu. At the same time, ryegrass, Sudan grass, saliva, and duckweed were raised to feed grass carp and fed 2 to 3 times a day.
5, timely application of fertilizer, cultivate natural food
When the temperature is low, the water and fertilizer should be raided to cultivate plankton that is suitable for the “fat and water fish†to feed and promote the rapid growth of carp. Every 2 to 3 days will be applied topdressing, each time the maturity of manure and livestock manure 100 to 150 kg. In summer, the temperature rises, and the Shinongjia fertilizer is easy to flood the pond, and can be changed to chemical fertilizers. It is applied once every 5 to 7 days, and fertilizers are applied at a rate of 2.5 to 5 kg per mu.
?
6, sets of specifications fish species, catch large in phases and stay small
Scientifically designed stockings, nesting, number of traps, number of traps, rounding and catching, catching three times a year, catching 500 to 600 kilograms, to achieve a balanced listing, and the remaining fish in autumn. And out of the pond. At the end of July, 6 to 10 cm of small fingerlings will be raised to prepare for the cultivation of large-sized fish species in the second year.
7, turn drugs splashing, timely prevention and treatment of fish disease
During the high-temperature period, 10 kg of lime per acre or 90% of crystal trichlorfon 250-350 g is used for slurrying and sprinkling, and bleaching powder or copper sulphate and ferrous sulfate are suspended on the floating bait stage of fish. For disinfection of the food field. In the epidemic season of grass carp enteritis, every 100 kilograms of grass carp is mixed and fed with 0.5 kilograms of garlic head and bait, and fed for 3 to 6 days to prevent grass carp enteritis.
