With rising temperatures, fish enter the growing season, especially in June and September, which is an important season for increasing fish production. Therefore, it is necessary to strengthen the management of breeding. The main measures are: First, the investment should be focused on raw materials, supplemented by green materials. Concentrates include full-priced pellets, bean cakes, cakes, wheat bran and rice bran. The daily feeding amount is 5% to 8% of the weight of the pond. In order to increase the utilization of bait, the number of feedings is generally 4 times a day. The bait requires fresh, mildew-free, non-deteriorating, and good palatability. Concentrates must be placed in the food court, and various green materials can be placed in floating frames. In summer, the water temperature is high and the weather is changeable. To prevent the fish from floating, you can invest more in the morning and at noon, and you should invest less in the evening. Second, rational fertilization in order to promote the continuous growth and reproduction of fish pond natural food organisms, provide natural food, reduce feed costs. Summer ponds should be suitable for fertilization. In summer, the temperature is high, and the water quality changes quickly. Fertilization adheres to a small number of times and is usually applied once every 5 to 7 days. Fertilization promotes the use of inorganic fertilizers and photosynthetic bacteria. Each time nitrogen fertilizer applied per mu, phosphate fertilizer 2 to 4 kg or photosynthetic bacteria 10 mg/kg, pig manure was fully fermented. When the transparency of the fish pond is too large and the weather is normal, it can be applied more than necessary; when the pond is muddy and the weather is abnormal, fertilization should be stopped. , And promptly change the water. Third, to adjust the water quality in summer high water temperature, fish food intake, excrement and more. Combined with feeding and fertilizer, it is easy to cause oxygen deficiency in fish ponds and affect fish growth. Prevention methods: 1, properly increase the water level, the depth of the fish pond should be maintained at 2 m or more, and often a small amount of fresh water, increase the water dissolved oxygen; 2, regular spill lime, every 7 ~ 10 d, with lime per every 15? 20 kg. Lime has the function of clarification of water quality, prevention of water quality aging, and increase of water body calcium. Scientific use of aerators, aerators have the effect of water agitation, aeration, and oxygenation. When using, according to the actual situation, flexible boot. 4, the use of water quality improver and biological agents, inhibition of harmful bacteria and improve feed utilization. Fourth, to prevent the floating head from sticking to the pool for three times a day, observe whether the fish has floating heads at dawn, check the eating and activities of turtles at noon, and check the eating conditions and signs of floating heads throughout the day at dusk. Timely remove the leftover grass and dirt to remove weeds from the pond so as not to pollute the water quality and affect the dissolved oxygen in the water. Tian Shui is warm. Feeding, fertilizer, large amount of organic matter in the water, oxygen consumption increased, the fish easily floating head due to lack of oxygen, especially hot nights or thunderstorm weather should pay more attention. When there are signs of floating head, new water should be added in time or aerators should be used to increase oxygen, and the amount of feeding should be reduced until feeding is stopped. When the floating head occurs, oxygenation measures should be taken immediately, and yellow muddy water can be added to the pond to add salt water. Generally, 10 kg of yellow mud water per acre is poured, and salt water lO kg is added to the water solution. After mixing, the whole pool is splashed. Fifth, the catcher can not only put some fresh fish on the off-season to increase the economic benefits, but also reduce the fish density, make the fish density reasonable, and make full use of the bait. In the middle or late July, a group of fish that have reached the market size will be sold. At the same time, a small portion of small-sized fingerlings will be added to the pond to grow large-sized fingerlings in the coming year. In August and early September, another part will be caught. Fishing should take place in the cool morning. Sixth, comprehensive disease prevention Summer is the peak season for fish growth, and it is also the peak period of fish disease. Should adhere to the "anti-emphasis on governance, prevention and treatment combined, early treatment of disease." Frequent illnesses include bleeding, enteritis, gill disease, and Chinese rickets. Routine management work should be done to disinfect bait, tools, and water. The food field was disinfected once every half month with 0 5 mg/kg strong chlorine extract. Every 20 days, soaking the feed with 3% saline solution for 5 days. Once the onset of disease encourages the use of environmentally friendly and improved fishery drugs, it is recommended that Chinese medicines and biological agents be used as much as possible. It is forbidden to use fishery drugs without “three certificates”. The “three certificates” means production license, approval document number and production batch number.

An Oxygen Concentrator is a type of medical device used for delivering oxygen to individuals with breathing-related disorders. Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen.

Generally, you can`t buy an oxygen concentrator over the counter. A doctor must prescribe it after they`ve completed a thorough medical evaluation. The doctors will also typically show the patients how to effectively use these concentrators while traveling and in their home.

Oxygen concentrators filter surrounding air, compressing it to the required density and then delivering purified medical grade oxygen into a pulse-dose delivery system or continuous stream system to the patient.

It`s also equipped with special filters and sieve beds which help remove Nitrogen from the air to ensure delivery of completely purified oxygen to the patient. These devices also come with an electronic user interface so you can adjust the levels of oxygen concentration and delivery settings. You then inhale the oxygen through the nasal cannula or special mask.
