Grass carp grows faster and yields more, but the meat is looser. In recent years, in some places, it has been subjected to embrittlement, that is, its meat has become brittle by changing its food structure. The embrittled grass carp is tight and crisp, not easy to boil, cut into fish fillets, fish silk is not easy to break. The technical points of grass carp embrittlement culture are introduced as follows:
First, embrittlement time. From the spring water temperature of 15 or more, the grass carp can start feeding until it stops. Embrittlement culture can not be less than 60 days.
Second, the pond conditions. Choose the pond with less silt, good drainage and irrigation conditions, fresh water, an area of ​​3-5 acres and a water depth of 1.6-2.2 meters for aquaculture. The best choice is to use flowing water. The selected pond should be cleaned thoroughly by conventional methods.
Third, stocking requirements. Choose 0.9-1.3 kilograms of each tail and have a healthy, disease-free grass carp. The selected fish should be disinfected with bleaching powder or salt and placed in a pond. The appropriate amount of 150-200 kg per acre is appropriate. At the same time, 50-60 white pheasants with a body length of 13-15 cm are stocked to control the water quality.
Fourth, feeding and management. The main feed is broad bean, plus a small amount of grass, can not add any other food. Feeding method: The grass carp to be embrittled is stopped for 2-3 days, then soaked shredded broad beans are fed, and a small amount of grass is fed. Normally, they are fed once a day from 8-9 am and from 2-3 pm, and the amount of feed each time is about 5% of the fish's body weight. It is necessary to step up the inspection of the ponds, remove the residual baits in time, and strictly prohibit the feeding of deteriorating feeds. After 60-70 days of feeding, fish can be harvested and marketed.
