The fish pond does not need to be fed at night. Usually feed the fish pond two or three times a day, and every time you feed it, it should be separated for a period of time, so that the fish can digest well, which is beneficial to its growth. At night, the fish will rest, so it is not necessary to feed at this time, which will not only waste feed, but also pollute the water environment, which is harmful to the health of the fish. In addition, you can feed less in winter, because the temperature is lower and the appetite of fish is not strong.

1. Feed selection: Fish ponds should choose suitable feed according to the types of fish. Common feeds are animal feed and plant feed, which can supplement energy and protein, but mineral feed and vitamin feed are also needed to supplement specific nutrition for them to avoid poor growth of fish.

2. Control food intake: The amount of food fed in fish ponds must be controlled. If too much food is fed for a long time, fish will easily suffer from gastroenteritis, which will affect their health. If it is not treated in time, it may also lead to their death. It should be noted that the scale of fish farming in fish ponds is too large, and it is very troublesome to treat them.

3. Treatment of residual bait: If there is residual bait in fish ponds, it is easy to cause a large number of microorganisms, which will then cause algae explosion. Once this happens, a large number of fish will die. Therefore, we must pay attention to cleaning up the residual bait at ordinary times and discharge the dirt at the bottom of the fish pond in time.
