Breeding management is related to the success of farming, proper management, high probability of success, improper management, it will cause losses or even failure. Therefore, scientific management is very important. Aquaculture management includes water quality management, food management and disease control.

I. Water quality management: The water quality of shrimp ponds is one of the main factors affecting shrimp production. Shrimp culture water first, which is the main part of aquaculture process management, and is the key to success. Changes in the water environment directly affect the growth of shrimp. In poor water environments, the food intake of shrimp declines, affecting growth. At the same time, poor water quality can encourage the proliferation of various pathogens, resulting in shrimp disease, which can lead to failure. Therefore, it is very important to maintain the relative stability of various water quality indicators during the breeding process. It is best to apply “Tianchen Fishery Fertilizer” on a regular basis every month to improve water quality, cultivate natural foods that shrimps like to eat, reduce the feed coefficient, and save the breeding cost. Shrimp pool water quality indicators: pH value between 8 ~ 8.6; water color brown, brown or green; transparency in 30 ~ 40cm; dissolved oxygen in 4mg / l or more; ammonia nitrogen is less than 0.1mg / l; nitrous acid The salt is less than 0.05 mg/l. Add water in the early stage, change the water according to the water quality in the middle and later stages, and regularly use microecological agents to adjust the water quality so that the water quality can be maintained well.

Second, bait management: 7 to 10 days before the shrimp seedlings use "Tianchen fishing fat" 2-3 kilograms of fertilizer per acre of water, then fertilizer pool, 15 days after the pool, generally do not feed, 15 days after the start of feeding compound feed, each Zhou assisted feeding 1 to 2 fresh live bait to speed up the growth rate. Two feedings were conducted on the previous day and three to four feedings were conducted on the middle and later days. The daily feeding amount was calculated based on 5% of shrimp body weight or depending on the shrimp feeding condition. The water temperature is high, shrimp can eat well and can be more appropriate vote, the water temperature is low and low investment, the water temperature is less than 15 °C do not vote. ?

III. Disease Prevention and Control: The prevention and control of shrimp disease should be based on the principle of “prevention as the mainstay and comprehensive prevention and control”. The water body should be disinfected regularly during the whole cultivation period. Generally, the disinfection should be performed after releasing the seedlings for one month, and then every two weeks thereafter. Secondly, every half or one month in the cultivation process, the whole pool is splashed with tea bran so that the pool water concentration is 5 to 10 ppm, which can stimulate the shrimp shell and accelerate the growth.

Fourth, daily management: stick to the morning and evening patrol once, check whether there are any damage to the facilities, observe changes in shrimp pond environment, especially the observation of the water color, shrimp activities, and find problems in a timely manner.
