1. What if the fish in the fish pond always dies? If the fish in the fish pond always dies, it is necessary to change the bottom material and pay attention to cleaning up sundries. The main reason why fish die is that the environment is not good, and there are too many sundries under the water, which leads to the accumulation of a large number of harmful substances and the breeding of bacteria and microorganisms, thus affecting the health of fish and even leading to their death. The method of changing the bottom is very simple, and enzymes or negative films can be used. In addition, the water quality should be adjusted well, which can increase the immunity of fish.
2. Why do the raised fish die1. There is no pond clearing: After the new fish pond is built, it needs to be cleared. Although there is no silt at the bottom of the pond, there will inevitably be some bacteria. If the pond is not cleared, harmful bacteria in the water may invade the fry, resulting in a large number of deaths. Usually, after building a fish pond, it needs to be exposed to the sun for a period of time, which can eliminate a large number of bacteria. Then put a little water into the fish pond, and sprinkle bleaching powder or quicklime on the whole pond. These two drugs are sharp tools for sterilization and disinfection.
2. Poor water quality: Poor water quality does not necessarily mean turbidity of water body. As the saying goes, when water is clear, there will be no fish, and too clear water can't raise live fish. Usually, after releasing water, it is necessary to apply fertilizer properly. Although these fertilizers can't be used as feed for fry, they can promote plankton to multiply in large numbers, so that fish can have something to eat. Of course, we should also pay attention to testing water temperature and hardness to see if the water body is suitable for the growth and survival of fish.
3. Fish fry problems: Apart from fish ponds and water problems, if the quality of fish fry is not good, a large number of fish fry will die. This is mainly because its constitution is too weak to adapt to the pond environment, which leads to stress reaction and death. Generally, it is necessary to make clear the source of fry. It is best to buy less and test its quality first. If it is good, buy and put it in on a large scale. If a small batch can't be raised, consider changing to other sources.
