Why does the silver carp float on the water?
There might be the following reasons why the silver carp floated on the surface of the water: 1. ** Water Quality ** - ** Water Poisoning **: When toxic substances in the water are produced from the bottom of the water, the silver carp will swim to the surface of the water with a lower concentration of toxic substances in order to avoid harm. In this case, they may float on the surface. For example, in some fertile water cultivation waters where chicken manure was added, the input was too large and the water quality was not adjusted. This situation might occur when water body turbulence occurred. - ** The water is rich in organic matter and consumes oxygen **: If unfermented feces and urine are discharged into the pond, these substances will naturally consume a large amount of dissolved oxygen, causing the silver carp to float. - ** Hypoxia **: The lack of oxygen will cause the silver carp to float to the surface of the water, but it must be distinguished from poisoning. For example, one could turn on the breather and see how many fish surrounded the breather. If the fish were not near the breather, it might not be a simple lack of oxygen. 2. ** Disease factor ** - ** Rotten gills **: If the gills of a fish have rotten gills, it will affect the dissolved oxygen in the water to enter the body through the small gills, causing the fish to float on the surface of the water. Rotten gills could be caused by parasites, such as the wheel worm, or it could be caused by fungi or bacteria. 3. ** Meteorological factors **: For example, cliff-like cooling and other meteorological factors may cause a large number of wild silver carp to float to the surface. 4. [Human factors: In some cases, such as Xichong's Jiulongtan claiming that the silver carp were of the quality of evolution water, but they were secretly salvaged. Human factors such as disturbance during the salvaging process could also cause the silver carp to float on the surface.] The novel " Watching the Moon on Fish Island " is equally exciting.

Is the life of the silver carp strong?
Silver carp had a certain tenacity. On the one hand, even if the silver carp was cut open and placed there, its heartbeat would still maintain a very slow beat, which indicated that it had a certain vitality. In a dead ditch with ten to twenty big silver carp weighing more than ten catties, they could be caught in a specific way without sucking up the water, which also implied that they could still survive in a relatively harsh environment. There were also fishing friends who caught silver carp and bighead carp with 84 hooks and fishing gear all over their bodies. They could still bite the bait with wounds all over their bodies and still survive after many fishing lines were cut off. These situations reflected the tenacity of the silver carp. On the other hand, silver carp had very weak vitality after coming out of the water and were easy to die. This made the silver carp sold often "turn over their white belly". Even if some of them were not dead, they did not look fresh. Moreover, silver carp had weak vitality during transportation and were not easy to transport over long distances, making it difficult to see silver carp in some regional markets.

Can silver carp be raised?
Silver carp could be raised. Under the conditions of pond culture, if there was enough food, the fish could grow to 500 - 800 grams in the year, and the weight of the three-year-old fish could reach 3 - 4 kilograms. There are certain requirements for the stocking of its fry. In the middle and late May, when the water temperature in the pool is stable above 18 ° C, it is suitable to put in the silver carp, and the density is 3 - 5 fish per square meter. In terms of feeding and management, after the fish entered the pond, they mainly fed on the zooplanks and feed scraps. When the adult fish are cultivated, the size of the overwintered fish is 100 - 200g/fish, and the stocking density is 0.4 - 0.5 fish/m2. There were also corresponding standards for overwinter management. For example, the overwinter density was generally 0.3 - 0.6 kg/m2, and the overwinter pond should be relatively clean and have good water conservation. At the same time, it should be noted that the ability of silver carp to withstand low oxygen is extremely poor. If there is no oxygen in the water, they will immediately float to the surface, and some will die very quickly. Therefore, it is necessary to always open the breather and regularly use products such as Zhongbangbang Jiuyang that can improve water quality and increase oxygen. Silver carp belonged to the category of inter-cultured fish, which could be inter-cultured in ponds that mainly raised carp, Crucian carp, grass carp, and blunt bream. The pond selection and water quality requirements were basically the same as that of the main carp. In addition, the seedlings must be inspected and quarantine before they are released. The seedlings must be of pure quality, healthy, and neat. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
