Thai shrimp culture was gradually developed in the early 1980s. Since 1992, a variety of shrimp diseases have been occurring continuously, among which yellowhead virus is more harmful than other virus diseases. However, shrimp aquaculture production has not only not been reduced, but also continues to increase. For example, shrimp production in Thailand was 162,000 tons in 1991: it was 182,000 tons in 1992 and 210,000 tons in 1993 (the total shrimp production in the world was 640,000 tons). It was heard that in 1994 it reached 250,000 tons, and in 1996 it was 160,000 tons (the world's shrimp production was 700,000 tons). The reason for this is the emphasis on the prevention of shrimp diseases. Their experience is worth learning from. They are described as follows: I. Maintaining an Excellent Environment for Shrimp Farming The Thai people have an early understanding of environmental protection. The government has clearly defined the relationship between the development of shrimp production and the strengthening of environmental protection in the guiding ideology, and has formulated a series of regulations on the planning and construction of shrimp farms. Emphasizes the reasonable layout of shrimp ponds and emphasizes maintaining ecological balance and environmental protection. The construction of shrimp farms on state-owned land requires government approval before construction. In the construction of shrimp ponds, we must first carry out the demonstration and assessment of the environment, fully consider the environmental load and reflect the disease prevention requirements. The main considerations are water resources, water quality, and sediment quality. Design and construction of high standards, all kinds of supporting facilities to complete. 2. Before each shrimp is cultured, the shrimp pond should be completely dredged and disinfected. The shrimp scavengers should use clearing pond disinfection as the basis for disease prevention. Each year, two shrimps should be raised, and the two pools should be cleared. And every time I clear the pool, I insist that the bottom of the pool is clean. Their method, d, was dry dredging and the use of a bulldozer to push out the embankment. Second, it is wet dredging, and the water clearing unit removes silt. The dredging was very thorough. Some people claimed that wearing leather shoes went to the end of shrimp ponds, and there was no sludge. Then plowing the sun on the bottom of the pool, lime, after thorough disinfection, and then irrigating new water. 3. The measures for the strict control of water quality are as follows: 1. Shrimp farms generally implement separate irrigation and drainage systems, and take water from deep or offshore locations to avoid introducing contaminated water sources. 2. It is universally practiced that the reservoirs and shrimp ponds are in proportion to each other, and the seawater introduced from the sea area to the storage tanks will be treated by sedimentation, disinfection, and monitoring before entering the shrimp ponds. The ratio of storage tanks to shrimp ponds is generally 1:4, while others are 1:2. 3. It is important to pay attention to the aquaculture of the shrimp ponds so that the shrimp ponds maintain a certain algae phase and maintain a water clarity of 30-40 cm. Phytoplankton in water can consume ammonia, hydrogen sulfide, and other harmful substances, and can increase oxygen in the water, so that shrimp ponds maintain good water quality. 4. It is after the sedimentation of the shrimp ponds that the sediments can be precipitated and discharged into the sea. 5. Strictly control shrimp pond water exchange, whether to change water, and mainly based on monitoring data to determine aquaculture practices and water changes. Fourth, attach importance to shrimp pool aeration facilities supporting Thailand shrimp are generally equipped with aerator. Usually placed in the four corners of the shrimp pond, clockwise operation, both oxygen, but also make the water circulation. In this way, the bottom of the pool is very clean, the dirt is concentrated in the center of the pool, and there is an inverted siphon suction hole, so that the dirt that flows to the middle is discharged through the drain hole. The aerator matching standard is 15-20 hp/ha. Many of them use imported aerators. Fifth, the use of high-quality feed in order to prevent shrimp pond pollution, to ensure the nutrition of shrimp, shrimp farming in Thailand are basically all with compound feed. According to the growth requirements of various stages of shrimp, they are prepared with complete nutrition. Good quality feed. From their basic formula for prawn feed, animal protein is predominant. The calcium raw material is also mainly fish and shrimp head powder. The proportion of vitamins is high, especially the proportion of vitamin C reaches 2.0-2.5 inches. Vitamins have immunity and are important substances in the prevention of shrimp diseases. At the same time, the relevant government departments of Thailand attach great importance to the inspection of feed quality, and regularly perform inspections from time to time on a regular basis. If it is found that the feed quality of shrimp feed plants does not meet the requirements, sanctions should be adopted. A good feed to ensure the healthy growth of shrimp is an effective measure to prevent diseases. For shrimp farmers in China, they also have experience and poor quality feed. Although the price is low, it is uneconomical. In recent years, we have used high-quality Guangdong-brand shrimp feed, shrimp production, high yield, and less disease, because high-quality feeds play an important role. Sixth, to prevent shrimp disease throughout the whole process of shrimp production for good viral shrimp disease, the best choice for the current control method is prevention, and the secret of their success lies in prevention. What has been discovered and used at the end of the year and their preventive methods, such as the above-mentioned, are to improve the management of the ecological environment, use engineering and technology to strengthen management measures, maintain the stability of the sea environment, and the fine environment of shrimp ponds. The ultimate goal is to prevent the occurrence of shrimp disease and stabilize production. If a shrimp pond is encountered, it must undergo strict disinfection before it can continue to raise shrimp. The treatment process is: 1. Close all inlet and outlet ports and disinfect with more than 20ppm of chlorine. 3, after a week of stormwater selenium. 4, continue to dry after removing the sediment. 5, irrigation 1.4-1.6 meters, with 20ppm chlorine disinfection of pool water. 6, applied to chicken manure and chemical fertilizer culture water, transparency up to 3 Dewto centimeters. 7. After measuring no residual chlorine in the water, it is put in aquaculture. 7. The shrimp ponds with severe shrimp disease in the course of rotation should have poor natural conditions. The standard of the original shrimp ponds should be low, and shrimp should not be raised, and other types should be abandoned or revitalized. After large-scale occurrence of shrimp disease in Thailand, diseases and dead shrimps often occur at the top and east of the Gulf of Thailand due to unfavorable conditions. They breed the main producing areas to the south and west coasts. Some shrimp ponds, which are often caused by shrimp diseases, are reared to fish or used for leisure periods.
