Grass carp grows fast, has low feeding cost, and has a high market share. However, grass carp has a relatively loose meat and its cooking method is relatively simple. The embrittlement of grass carp is to make the meat hard and crisp by changing its food structure, and it is not easy to boil. Cutting fish fillets and fish fillets are not easy to break, but the taste is still delicious and is welcomed by consumers. The new technology for embrittling grass carp is introduced as follows:
First, the pond conditions to select the bottom of the pool less silt, irrigation and drainage conditions, fresh water, an area of ​​1300 square meters to 2,000 square meters, water depth of 1.5 meters to 2 meters of the pond as well. Clear the pond thoroughly by conventional methods. If you choose running water, the effect is better.
Second, the embrittlement season from the spring water temperature above 15 °C, grass carp began feeding until stopped feeding before, but to ensure that embrittlement time is not less than 60 days to 70 days.
Third, the stocking object selection weight of 0.75 kg / tail ~ 1 kg / tail of grass carp for the object of crisp stocking, requiring a healthy body, disease-free without injury. Disinfect the fish body with bleach or salt and put it in the pond. The amount of stocking per acre is 150 kg to 200 kg, and 50 to 60 fishes with a body length of 13 cm to 15 cm are used to adjust the water quality.
Fourth, feeding and management to broad beans as the main feed, plus a small amount of grass, but can not add any other food, otherwise affect the embrittlement effect. At the beginning, you can stop for 2 days to 3 days, and then feed a small amount of soaked shredded beans until grass carp eats. After the timing, positioning feeding, supplemented with a small amount of grass. Usually, the feeds are fed once every 8 to 9 and from 14 to 15 o'clock. The amount of each feed is about 5% of the fish's body weight, and the food is consumed within 1.5 hours to 2 hours. Strengthen water quality management and regularly add new water to ensure transparency of more than 40 cm. Timely removal of residual bait, is strictly prohibited feeding degenerate feed. Regularly prevent and treat fish diseases, timely rescue floating heads and prevent dead fish. In this way, after 60 days to 70 days of embrittlement, the market quality requirements can be achieved. Generally, about 100 kg of adult fish can be produced per acre. At this point the pond fish can be completely captured for the next batch of embrittlement.
