According to the inspection result, the time To adjust the amount of feed, it is necessary to prevent the lack of feeding, but also to prevent overfeeding, depositing the bottom of the pool and spoiling water quality, causing shrimp disease.
3. Disease Prevention and Control In the hot season, various pathogens are extremely active, and shrimp are susceptible to various diseases. Therefore, it is extremely important to prevent shrimp diseases. You can use bleach or active iodine solution once a month to prevent bacteria infection. If ciliates appear, they must first be killed with “Crayon Net†and then once a week to use bactericidal drugs again to prevent secondary infection with bacterial diseases.
4, prevent floating head intolerance of hypoxia shrimp, the higher the dissolved oxygen requirements of the water body, and the lack of oxygen leading to floating shrimp pond is often a common cause of failure of shrimp breeding, in order to prevent the occurrence of such phenomena, on the one hand The rational use of aerators should be strengthened on the other hand, and the weather and water quality should be closely watched. Once problems are discovered, the causes must be analyzed in a timely manner and decisive action should be taken.
High-temperature management measures for pond cultured shrimp
1. Water Quality During the period of high temperature regulation, water quality tends to deteriorate, affecting the growth of shrimp. In order to reduce the water temperature, the pool water should be deepened at this time, and the minimum water level should be maintained at 80 cm or more.
