water? If the water in the newly dug fish pond is muddy, you can change the water appropriately and add water once every 7-10 days, 15-20 centimeters each time. Regularly use quicklime to adjust the water quality, 15-20 kg per mu. In addition, it is necessary to add oxygen to the water to increase the dissolved oxygen at the bottom of the water and avoid the growth of anaerobic bacteria, so that the bottom of the water can be kept clean and hygienic. You can also plant some aquatic plants or cultivate some algae to improve water quality.
? 1. The substrate is not good: The main reason for the turbidity of the water is that the substrate is not good. Usually, before fish farming, the pond must be cleaned. Cleaning the pond is not only to disinfect, but also to clean up the silt at the bottom of the pond. If the silt is too thick, anaerobic bacteria are easy to breed, which leads to the deterioration of the water body, and the water will become turbid.
2. Improper feeding: Fish need to be fed, but do not feed too much. Fish fry are fed with rotifers and other plankton, if the amount is not well controlled, resulting in a large number of reproduction, it will also make the water turbid, and feeding more other feed will lead to the deterioration of the water.
3. Insufficient oxygen: Fish ponds also need oxygen, especially in deep places. If the oxygen is insufficient, the substrate will deteriorate and anaerobic bacteria will multiply. In order to avoid this situation, an oxygen pump must be installed to oxygenate the water.
