During the cultivation of shrimp in paddy fields, a large amount of moss often appears in water bodies such as fish nests, fish ditch, and fish slips. Due to the rapid growth of moss, large amounts of nutrients are consumed in the water, and the water quality quickly becomes thinner, which seriously affects the growth of natural food organisms and affects the normal development of the shrimp. In addition, shrimp swim in moss and often die because they cannot swim. Therefore, the removal of moss is an important measure in the culture of shrimp. Several prevention methods and precautions are introduced as follows:
First, prevention and treatment methods?
1. Thoroughly clear the ditch with 75 kg of lime per acre. ?
2. Organize manpower to eradicate moss and fertilize it properly to promote the reproduction of plankton in the water, reduce the transparency of the water, and inhibit the sprouting of the moss. ?
3. Each square meter of ditch is covered with moss with 75 grams of ash to make it die due to lack of sunlight.
? 4. Each cubic meter of water with 0.5 grams of copper sulfate dissolved in water after the Quanchiposa, moss should be sprinkled more densely, two days later for 1/3 of the new water. ?
Second, pay attention to matters?
1. Copper sulfate is a heavy metal salt, and its use effect is affected by the temperature, pH, and hardness of the water body. The higher the temperature, the greater the toxicity; the higher the hardness and pH, the lower the toxicity. The application should be based on local conditions, flexible use, while taking into account the tolerance of copper shrimp to copper ions. ?
2. When using copper sulphate, it is necessary to measure the volume of the water correctly and observe the reaction of the shrimp for a long time (at least 10 hours). If there is any adverse reaction to the shrimp, it should be immediately filled with new hydrolysis. ?
3. It is best to use medication on a sunny day around 9am.
