2. When the management of field water is raining or flooding, the security of the field ridge should be strengthened. Pay attention to the smoothness of inlets and outlets and the effects of fish-blocking facilities. If there is any blockage or damage, promptly clear and maintain them. It is necessary to adjust the depth of water according to the needs of rice fields. The principle of adjustment is rice-based and proper care of fish farming. Before the shallow paddy fields and the rice fields are fielded, fish ditch and fish gills must be inspected to ensure that there is enough space for tilapia to swim. If it is unable to solve the impact of the sun on the fish, it should try to transfer the fish to other rice fields to continue feeding.
3. Use of Chemical Fertilizers and Pesticides When applying chemical fertilizers, the dosage should be controlled. Use 4 to 5 kilograms of urea or 5 to 8 kilograms of ammonium sulfate per acre. Use a small amount for multiple applications, or mix fertilizers directly with soil into pellet fertilizers. Applying to the roots of alfalfa, not only does it use less fertilizer, but it also has high fertilizer efficiency and it is also safe for tilapia. Generally do not use ammonia as top dressing, otherwise tilapia may easily be poisoned. The spraying of pesticides in tilapia-producing rice fields requires the effective prevention and control of rice pests and diseases and the loss of tilapia. Generally use high efficiency and low toxicity pesticides. It is forbidden to use highly toxic pesticides such as fish essence, toxaphene, 233, 666, and sodium pentachlorophenol. When the application of pesticides can be appropriately deepened to reduce the concentration of pesticides falling into the water. Drugs should be sprayed on the leaves and stems of rice as much as possible to improve the effectiveness of pest control and to reduce the harm caused by drugs falling into the water.
4. Tilapia prevention and treatment in fish disease Once tilapia is cured, treatment is difficult. Therefore, besides the need to dip and disinfect fingerlings before they are placed in paddy fields, bleaching powder should be regularly sprinkled in the fish ditch, gills, or the entire paddy field at a concentration of 2 mg/l, or 90% dichlorfon The concentration is 0.3-0.5 mg/l. Spilling crystal trichlorfon can both prevent fish diseases and prevent and control rice diseases and insect pests.
5. Harvesting of tilapia by adult fish catching in paddy fields usually takes place after rice is harvested. Before harvesting fish, first clear the fish ditch, then slowly release water so that the tilapia can enter the fish ditch and fish culvert automatically with the water, and use the fish net to collect the fish at the outlet. If the catch is not clean at one time, it can be re-irrigated and the collection repeated.
