At present, during the high-temperature season, shrimp breeding is in the early stage of stocking and feeding. In order to ensure normal production, it is recommended to adopt the following measures:
1, seed stocking should avoid stocking at noon high temperature, the surface temperature of the pond at noon high, not suitable for the survival of shrimp seedlings, prone to high temperature dead seedling phenomenon, in the morning or evening, when the water temperature is reduced after the stocking is relatively safe.
2. Farmed shrimp ponds and paddy fields can be filled with water to a certain depth, preferably reaching more than 0.8 meters. Ponds or rice fields increase the number of stocking plants and reduce the water temperature so that the shrimps grow normally.
3, to strengthen feeding management, choose a good quality water quality stability, to prevent the loss of feed water pollution, the amount of feeding should be appropriate, but the amount of feeding.
4. Strengthen water quality management. In high temperature season, ponds should be frequently injected and drained, especially water quality is deteriorated. Ponds with more blue-green algae should be multi-rowed and multi-irrigated to prevent dead shrimps with hypoxia, and drugs (including copper sulfate and clear pond agent) should be used. When killing blue-green algae or wild fish, it is necessary to pay attention to the correct use of dose, and pay attention to changes in water quality, timely injection of oxygen.
5. For the prevention of shrimp disease, due to continued high temperatures this year, shrimp disease may occur in the second half of the year. While strengthening feeding and water quality management, we must pay close attention to the status of shrimp disease. Once we have found bacterial red bump disease and red limb disease In the case of black shank disease, chlorine dioxide and other disinfectants should be used in a timely manner. At the same time, baits containing oxytetracycline should be administered.
