Since the summer of this year, due to the influence of the subtropical high, most parts of China have experienced continuous drought and drought, and the long time and wide range of droughts have seriously affected fishery production. The situation is very grim. How to minimize the damage caused by drought to fishery production is an important issue that urgently needs to be solved at all levels and by fishermen at all levels.
1. Pay attention to drought warnings and prepare for drought prevention. First of all, the vast majority of fishery production units and farmers should pay close attention to meteorological department's drought forecast, strengthen contact with the fishery technical department, and accept the guidance of the fishery technicians. Aquatic technology departments should pay close attention to meteorological department drought forecast, strengthen contact with fishery production bases and farmers, and recommend that they repair the pump and aerator to prevent emergencies. Proactively contact the relevant distributors of fishery and pharmaceutical supplies to arrange reserves of fishery medicines and materials such as bleaching powder, quicklime, bactericide, and water quality improver in order to meet the needs of the time. Secondly, we should establish a sense of drought resistance, make necessary preparations for drought-resistant materials, and do a good job of storage and water storage in the ponds, and maintain the maximum water capacity of the ponds in order to withstand the drought.
2. Active drought relief, reduce disaster losses. Organize the majority of cadres and the masses to actively fight drought and extensively develop water sources for drought resistance, timely replenish water through reservoir diversion, drill wells to find water, pump stations to raise water, dig ponds to store water, and repair additional irrigation facilities, etc., and dispatch droughts scientifically. With water. Scientific guidance, organize scientific and technical personnel to go deep into the grassroots to guide fishermen in scientific prevention and control, to avoid the outbreak of large-scale disease outbreaks. The seedling production units shall take timely measures to increase water supply facilities or repair and maintain the water supply facilities so as to ensure the seed production water. Strengthen the management of broodstock so that hatchery production can be expected to proceed. At the same time, the supply of seedlings is well organized to meet the needs of the fish farmers after the disaster to the maximum extent, so that the majority of farmers can promptly add enough fingerlings after the disaster to reduce the impact of drought to a minimum.
3. Strengthen aquaculture management and create a good breeding environment. Adhere to the early, middle, and evening patrol ponds, frequently check the fish-rejecting facilities at the outlets, find problems in time for repairs and reinforcements, and prevent fish escape. At the same time, it is necessary to set up a patrol duty shift system and pay close attention to changes in water levels to prevent the occurrence of stealing fish. Strengthen water quality management, timely remove residual baits, debris, and artificially increase oxygen in time to maintain a good culture water environment. Before the drought is lifted, it is recommended that the fish farmers reduce the amount of feed used for fertilizers, and adopt large catching and retaining methods to reduce the amount of pond fish and relieve pressure. Broaden sales channels, timely market the sale of commercial fish, reduce the backlog, avoid large areas of death due to lack of oxygen floating head; timely transfer of fish pond species difficult to use to avoid losses.
4. Strengthen fish disease prevention and prevent outbreaks of disease. The fishery technicians were carefully organized to comply with the requirements for the monitoring and reporting of aquaculture diseases, expand the scope of monitoring, increase the frequency of monitoring, find out the condition, report it promptly and deal with it in time, and prevent and control the spread and outbreak of the disease. We must do a good job of prevention and control, and conduct prevention and control of key aquaculture species and regional epidemics to ensure early detection, early diagnosis, early control, scientific and effective drug use, and harmless treatment of dead fish. Regularly throw lime, microbiological water quality improver, and enhance fish disease resistance. During the high season of fish disease, fish should be observed in the daily activities of the fish ponds and eating conditions, and abnormalities should be detected in time for fish disease examination and corresponding treatment. We must implement the principle of "prevention first, prevention and prevention of stress," and regularly disinfect the body of aquatic products by disinfecting water disinfectants and adding some internal medicines to the bait so as to prevent the occurrence of fish diseases. At the same time strengthen the management of input products to ensure the safety of aquatic products.
