1. In the late summer high temperature period, it is necessary to adopt shading and cooling, increase the amount of water to be changed, and strengthen the scrubbing and sewerage work. European oyster intensive breeding ponds generally need to exchange water at 1.2 times to 1.5 times daily. Japanese oyster intensive breeding ponds and earth ponds are required to have a flexible control of water exchange according to water quality and color. In addition, the physical and chemical indicators of pool water should also be regularly monitored to timely grasp the dynamics of water quality and take timely measures.
2. Typhoons are more frequent this year, and thunderstorms often lead to abrupt changes in the physical and chemical indicators of water sources and pool water, such as turbidity in water quality and large changes in pH values. Water quality mutations can easily lead to outbreaks of major diseases. The soil and water in the mountainous areas are acidic, especially when there are heavy rainstorms, the ponds should be stopped from adding turbid water, and should be added when the water source is clearer, combined with the use of suspended lime, etc., to precipitate suspended solids, clarify the pool water to kill pathogens, and improve the water environment. .
3. Scientific feeding should be used during the high-temperature period, and the amount of feeding should be properly controlled to avoid overeating. Feeding time is generally controlled within 20 minutes, eight minutes full, especially if the European high temperature period without limit feeding, easily lead to outbreaks of desensitization sepsis. At the same time, every five or six days a meal is stopped, splashed with drugs (such as potassium permanganate, chlorine disinfectants, etc.) for water quality improvement and disinfection.
4. The following precautions should be taken before and after the typhoon approach: Always pay attention to the weather forecast, prepare personnel, materials and necessary measures before the typhoon approach, and maintain the power circuit and related facilities (such as the power distribution panel must be firm, the generator must To prevent rain from getting wet and unable to start, the shading net should be tightly fixed with iron wire; etc.) Feeding should be properly adjusted to minimize or stop eating; at the same time, water quality regulation should be carried out using chlorine-containing disinfectant and permanganate Potassium, ecological water transfer and other drugs are processed. After the typhoon, it will generally face high temperature weather, and the amount of feeding should be gradually increased, not too fast, and add health-care drugs to the feed, such as eel multi-dimensional, attracting aquatic yeast, Vc, VE, and liver protection gallbladder (such as protection Heparin, hepatobiliary, gallbladder, etc.) to facilitate the increase in anti-stress ability and recovery of physique.
5. The main diseases in the high-temperature period are de-mucous sepsis, mad-sick disease, fungal rotting and Japanese roaches disease. The focus of daily aquaculture management and disease prevention is to maintain a good water environment and a reasonable stocking density, and to avoid the use of stimulant drugs. Disease treatment should give priority to improving the water environment, and then remedy the disease. During the treatment, do not blindly consider the medicine bath and stop eating for a long time. According to the condition, timely recovery of a small amount of feeding, proper addition of sensitive anti-pathogenic drugs in the diet and additives that help restore the function of the internal organs, timely recovery of the disease constitution, and more Good control of the condition and cure.
High-temperature quail cultivation precautions
At the end of summer, the weather is changeable, and high temperatures, thunderstorms, typhoons and other weather come in alternation, and maggot farming has entered the stage of high temperature management. The solar radiation intensity at this stage is relatively large, the pond water temperature is high, algae, bacteria and other organisms thrive, and it is easy to cause problems such as low transparency, high pH, ​​lack of oxygen, and sudden change of water quality in the pond water body. To address the climate and water quality characteristics of this stage, the following points are noted:
