I. Anti-pollution In order to ensure the safety of goldfish at night, cleaning work should be done every evening. In addition to removing the remaining bait, excrement, and algal corpse in the tank, the pool water contaminated with organic matter needs careful observation. If there is a thunderstorm in the evening weather, cleaning should be completed before the storm. The night observation work after the rain should be particularly careful, and the problems should be promptly taken to prevent the boring cylinder from causing unnecessary losses. Second, anti-anoxic goldfish in the summer is best to use the first combined with clean water, green water, in case of continuous raining Mei period, should be extracted daily or every other day a small portion of raw water, then add the same amount of new water. The water temperature for water change and water injection strives for balance, and the general temperature difference is limited to within 0.5°C to 1°C. When the outdoor fish pond encounters frequent rainfall, the photosynthesis of algae weakens, and the harmful gases generated by the decomposition of organic matter in the water cannot be completely absorbed by aquatic plants. It is easy to spoil the water quality. Once the water is extremely turbid or the dissolved oxygen is extremely low, the water should be changed in time. In addition, the stocking density should not be too large. Third, anti-asphyxiation goldfish rearing in aquariums, with particular attention to the sun's exposure, when conditions permit, can be inflated in the pool, especially at night, can effectively prevent the suffocation of goldfish. Family fish tanks should be placed on well-lit, ventilated balconies or patios. The selection of fish tanks should be based on large circular cylinders with a large mouth and small bottom, or tubs, aluminum basins and plastic basins with short body walls, shallow mouths, and wide mouths. The water level is stable at 20 cm to 25 cm, which is convenient for dissolved oxygen. Fourth, anti-heatstroke summer afternoon, the water temperature is usually up to 38 °C ~ 40 °C, unshaded fry or adult fish, often due to heat and light stimulation and sudden heat stroke, severe breathing difficulties, pale faded, lost Perceived, it floats on the surface and it is difficult to cure. Therefore, curtains should be shaded before 8 o'clock in the morning of midsummer to prevent the pool from rising too fast due to the sun exposure. For those with mild heat stroke, change the water temperature or change the water level in time. 5. Anti-anoreous goldfish, once it encounters hot weather or continuous rain, will produce appetite. At this point should choose to use live leeches to feed goldfish, and to do less feeding a lot of meals, 10 minutes to 20 minutes to finish eating is appropriate; can also be fed by 1/3 of the amount of spring feeding. Juvenile fish can increase the amount of feeding. VI. Prevention of Diseases In the management of midsummer, not only should observation at night be strengthened to prevent the suffocation of fish, but also the observation of fish body surface, activities, foraging, feces, and water color during the day should be strengthened. In feeding, if the goldfish “top food†is found to indicate indigestion, or if the appetite is low, the next day should stop eating or reduce the amount of feeding. For the older goldfish, it must be guarded against its silent death. For juvenile fish, we must carefully observe the body surface, whether it suffers from white spot disease, and find that goldfish have abnormal performance. You can spill 1% salt or 0.2% mercuric chloride solution in the fish pond, and reduce the amount of baits, 2 to 3 times. Second, it can ensure the health of young fish Chunmee Green Tea,Chunmee Green,Loose Green Tea,Osk Green Tea Hunan Junshan Yinzhen Tea Industry Co.,Ltd , https://www.junshan-tea.com Summer climate, sometimes heavy rain.
