The high dissolved oxygen requirement of the shrimp culture, the low survival rate and the impact on the yield, the raising of the survival rate of the shrimp culture and the increase of the output value of the production are as follows: First, clear pond shrimp: Before stocking, the pond should be exposed to the sun, with lime dissolved water spilled disinfection; there are moss, green algae pond, but also to use a copper sulfate pool spray once. Digging a pool of shrimp ditch in the pool, in order to facilitate the pool of water storage, but also easy to catch shrimp. Green shrimp pond mixed flowers, white peony is appropriate, not mixed mullet, herring. When stocking, the specifications should be the same, body length 1.5-2 cm, 2.5-30 thousand per mu control. In order to prevent bacterial infections caused by bumps, around mid-March, with active iodine solution, Quanchip is splashed once. Second, set the hidden objects: shrimp are afraid of strong light, in the strong light environment, the phenomenon of self-inflicted significantly increased. Therefore, properly shading the water surface. It is generally produced with water grass, water duckweed, and willow technique, etc. It has hidden objects that are easy to inhabit and avoid light (especially when the temperature is high and heat is too hot) and to avoid enemy enemies and similar attacks. The cover of aquatic plants is generally controlled at about 20% of the total surface area. Third, water quality management: The amount of water-soluble oxygen in shrimp culture is not less than 5 milligrams per liter of water. The water level in the pond should not be too low and it should be kept at 50-60 cm. Every 7-10 days, fresh water is added once; the amount of water changed every time is controlled at 20-30 cm. In a pond with a relatively thin water quality, 200-400 kilograms of fermented organic fertilizer should be piled and fertilized to improve the natural animal diet. In ponds with more water quality, after the water temperature rises, an inorganic fertilizer is applied, which is 5-7 kg per mu. Fourth, scientific feeding: water temperature 8-10 °C began feeding, rose above 18 °C, it is necessary to feed in time. Green prawns are based on predatory foods, and the protein content must be 30% or more (35% pups). Start once a day, throw wheat bran, bean cake or pelleted food, and add animal feed such as fish meal. Feeding amount accounts for 3%-6% of shrimp storage ponds, according to the situation of eating and drinking, timely increase and decrease adjustment. After April, it is a frequent stage of shelling, and it is necessary to increase the amount of animal foods such as oysters, snail meat, and quail meat to prevent self-mutilation. Fifth, timely arrest: shrimp mature early sexual reproduction, strong, easy to form several generations Tong Tong. In order to avoid antagonism between size and size, we often use dip nets or fish cages such as shrimp cages to catch up and leave small markets, which can increase unit production and increase economic efficiency. 5 Axis Cad Cam Dental Milling Machine is the champion in dental field.
