Recently, some areas in our country have been hit by heavy rain or heavy rain, which has caused floods and floods. Many fish ponds have been flooded or devastated, resulting in a certain impact on the production of fish culture. Therefore, in flood-prone areas, targeted production and self-rescue measures and methods should be adopted according to the different levels of fishpond disasters, among which are:
1. Rehabilitate the Tanggu and reduce the water level Where damaged ponds (also known as pond bases in some places) must be quickly repaired and heightened and reinforced to lay the foundation for fish farming and drainage. At the same time, we must pay close attention to the drainage of fish ponds, reduce the water level of fish ponds, and restore the water depth to 2 to 3 meters so as to facilitate feeding and management.
Second, determine the pond fish, timely fill up the fish on the fish or fish to escape the fish pond, reservoir ponds are often unclear, so after flooding fish ponds should be checked once to determine the amount of fish stored According to the situation of fish escape, the species of the corresponding regulations and the corresponding number of fish species shall be added in time. The severe ponds that escape fish should choose stocks of fast-growing species and accelerate cultivation to ensure that they are harvested and marketed in the same year.
Thirdly, disinfecting fish ponds and preventing storms and floods in fish diseases will cause many rivers to connect with fish ponds, which can easily cause epidemic or infection of bacterial fish diseases. For this reason, fishpond disinfection should be done well in the restoration of production. According to experience, the use of quick lime is better, the dosage is 20 kg to 25 kg per mu, but bleach powder can also be used instead. The dosage is 1 kg to 1.5 kg, and the whole pool is splashed with water. In addition, if there is a source of medicine, it can be used for the prevention and treatment of orally taken antibacterial drugs, and through water disinfection and medication, comprehensive prevention of fish disease infection and outbreak of epidemic fish disease.
Fourth, rational feeding feed, strengthen feeding management In the event of flooding, many fish ponds to reduce the feeding, and now must be fed to feed to restore feed. The fed food should be fresh and nutritious. The fed water and dry grass should be free of mud and impurities, and should not be fed with modified feed or moldy grass. Second, the amount of feed should be within 2 hours to 3 hours. After eating, the fodder will be eaten in the afternoon before feeding it, but also depending on the feeding conditions. The third is to feed the concentrate regularly, and feed it twice in the afternoon. The fodder is fed in the afternoon and the feed is given in the afternoon. Feeding allows the pond fish to eat well and accelerate growth.
In addition, depending on the quality of fish ponds and the loss of fertilizers after floods, efforts should be made to fertilize and cultivate water quality, so as to ensure that ponds and ponds after the flood and flooding are often used to keep the water quality constant, and to reduce or avoid fish floating and Get sick and promote the health of pond fish.
