Grass carp culture technology
The embrittlement of grass carp is mainly due to the change of the food structure of grass carp to make the meat crisp. After the embrittlement of grass carp called "crispy meat oysters" (Canton grassland called grass carp fish), the meat is hard and crisp, not easy to cook, even if cut into fish, fish silk is not easy to break, the meat will instead It is more delicious and unique, so as to meet the special taste requirements of consumers and improve the market competitiveness and aquaculture efficiency of grass carp. So, how can we raise crisp meat soup? 1. Breeding conditions. Grass carp embrittlement culture can be done either in a pond or in a cage. Pond requirements: less silt in the bottom of the pool, adequate water supply, good water quality, no pollution, easy access to water, area of ​​1330 to 2000 square meters, water depth of 2 meters or so, according to conventional requirements before restocking clear pond. The cages can be installed in the leeward sunny areas of lakes, reservoirs and rivers. Water requirements: no pollution, rich dissolved oxygen, water depth of 4 to 7 meters, flat bottom and waterless plants born. A fully enclosed cage with a size of 5m 4m and 2.5m and a mesh size of 0.05m is used. A 30-mesh gauze pad is placed on the bottom of the cage as a feeding platform to prevent feed loss. The new cages should be launched 7 to 10 days in advance to soften the boxes to prevent bruising. The used cages should be cleaned and soaked in 5% lime solution for 30 minutes. 2. Fish stocking. Choose grass carp, which is robust, harmless, and disease-free, and has an average tail weight of 0.5 kg, as a fish species, with a pond stocking capacity of 150-250 kg/mu and a cage stocking capacity of 15-20 kg/m2. In order to regulate the water quality, each mu of ponds can be stocked with 50 to 60 tails of oysters and breams with 0.13 to 0.15 meters in length, and 0.13 to 0.15 meters in length per square meter of cages.鲢, 鳙 species of 1 to 2 tail. Before stocking, the grass carp is best immunized. If unconditional, the fish can be soaked in 4% saline solution for 5 to 10 minutes. 3. Embrittlement season. Feeding of grass carp starting from spring temperatures of 15°C or above can be carried out before the winter season. If the breeding mode is carried out in rounds of catch or in batches, the time for each round (batch) of embrittlement should not be less than 60 to 70 days. 4. Aquaculture management. The feed is dominated by high protein beans, plus a small amount of grass, but no other feed can be added. At the beginning, you can stop for 2 to 3 days, and then feed a small amount of soaked broad beans (weak beans can be soaked with 1% saline for 12 to 24 hours). After the grass carp can feed normally, it can be fed regularly and quantitatively. Under normal circumstances, feed every day at about 8 o'clock in the morning and at 5 o'clock in the afternoon. The specific feeding amount should be adjusted according to the feeding conditions of grass carp and the change of water temperature. When the water temperature is 16°C～19°C, the daily feeding amount is 1.5%～2% of the body weight of grass carp. When the water temperature is 19°C～22°C, the daily feeding amount is 2%～3% of the body weight of grass carp and the water temperature is 22°C～25°C. The daily feeding amount was 3% of the body weight of grass carp, and the daily feeding amount was 3% to 4% of the body weight of grass carp when the water temperature was 22°C to 25°C, and the daily feeding amount was 4% of the body weight of grass carp when the water temperature was 25°C to 28°C. ~ 5%, water temperature 28 °C ~ 30 °C when the daily feeding amount of grass carp weight 5% ~ 6%. The daily management work is the same as that of grass carp.
