to build a fish pond must pay attention to the choice of location, usually near the river or lake, so close to the water source, can greatly reduce the cost. It should be noted that the nearby water source must not be polluted, otherwise the fish can not be raised alive. In addition, we should consider whether the traffic is convenient and how the power supply is.
of water source The water consumption of fish ponds is relatively large, so it is necessary to ensure that the water source is clean and sanitary. It is not realistic to use tap water, so only river water or reservoir water can be used. Fresh water should be injected into the fish pond regularly, which can prevent the deterioration of water quality, avoid the occurrence of hypoxia and other conditions, and is also conducive to the reproduction of plankton.
of the pond is also critical. Usually, there is not only one pond for fish farming. Fish fry and adult fish must be raised separately. Fish fry needs an area of 3-5 mu, and the water depth is about 1-1.5 meters. Growing fish needs an area of 8-10 acres, so that the fish have enough space to move around, so as to avoid squeezing each other.
If the dealkalization pond is a newly built cement pond, it needs to be dealkalized before fish farming. Dealkalization usually uses white vinegar or glacial acetic acid, which is poured into the pond and soaked for three days, then drained and rinsed several times. In addition to dealkalization, attention should also be paid to cleaning the pond. Quicklime or bleaching powder can be used to sprinkle the whole pond for sterilization and disinfection.
